AB  - In the paper, the analysis of the bearing capacity of the pile and the redistribution of the
load on the pile toe and shaft was carried out. The tests were carried out by a static load test (SLT)
incrementally increasing the compressive force on the test pile, and the tension force on the anchor
piles. The test system consisted of one test pile and two anchor piles with a reaction beam. Two
tests were conducted according to the same test program, where the test piles were of the same
length, while the length of the anchor piles in the second test was increased. In the first test, the
anchor pile failed, while in the second test, the test pile failed. Based on the achieved limit values of
settlement of the test and anchor pile, the bearing capacity of the test pile at the toe and shaft was
determined. Subsequently, a CPT test was carried out and the bearing capacity was calculated
according to the LPC-CPT method.

Boiler House for the energy utilization of waste and chimneys. Next to the boiler house, the
construction of a Bunker for waste storage is planned, which is founded at a depth of 6.0m below
the top of the boiler house's base plate. Based on the conditions of limited settlement, the
foundation of the boiler house was envisioned on drilled piles, while a hidden pile wall was
designed to protect the foundation pit of the bunker, which has the function of preventing large
deformations of the boiler house structure and does not jeopardize its stability. Calculations of the
bearing capacity of the piles based on the soil parameters from the geotechnical study are
presented, as well as the results of the pile tests with axial vertical pressure force.

upoređenje vrednosti dobijenih na osnovu navedena dva postupka.
2. Eksperimentalno ispitivanje na strukturi nosača kranske staze pod delujućim
opterećenjem (realna struktura u eksploataciji), direktno merenje ugiba usled
delujućeg opterećenja, posredno izračunavanje ugiba primenom razvijenog
numeričkog postupka proračuna na osnovu izmerenih vrednosti dilatacija u
osnovnom materijalu i upoređenje vrednosti dobijenih na osnovu navedena dva
postupka.
3. Razvoj i provera rada mernog mehatroničkog sistema za nadzor ugiba grednih
struktura praćenjem dilatacija u osnovnom materijalu, u koji je implementiran
razvijeni numerički postupak proračuna, na eksperimentalnom modelu

AB  - This paper focuses on the study of the strength of facade sandwich panels used in building construction. The paper describes the results of experimental and numerical research on the behavior of sandwich panels made of polyisocyanurate core (PIR) and their structural connections when exposed to tensile and compressive loads. In the initial phase of this study, laboratory tests were performed to determine the physical and mechanical characteristics of the material from which the sandwich panels are made. Laboratory tensile and compression tests were performed on small samples of sandwich facade panels. In order to verify the obtained results, they were compared with the numerical analysis performed in the ANSYS software. The numerical model was found to accurately predict the results of the laboratory tests, suggesting that the model can be used to predict the behavior of these panels under different loads in service. The study showed that the foam core sandwich panel exhibits excellent mechanical properties. The results indicate the suitability of foam-based composite structures in the construction industry for various applications, such as roof and wall structures. The findings of this study may help in the development of lightweight and durable construction materials for the industry.

AB  - Designing, constructing and putting into operation a hydroelectric power plant includes complex
tasks. Stresses of turbine and hydromechanical equipment of hydro power plants arise during the
production of parts and assembly of equipment (residual stresses), in the process of performing
functional requirements in exploitation and in the disturbed process of exploitation.
After several decades of constant exploitation of the horizontal bulb turbine, which is an integral
part of the hydroelectric power unit, empirically, the formation of a crack occurs in the turbine
shaft due to the influence of corrosion, erosion and cavitation.
Through experimental tests and calculations it has been determined that values of bending stresses
of the turbine, which occur due to the action of fatigue and corrosion, as well as stress
concentration, are bigger than 25 MPa for flanges exposed to water, and in other case bigger than
40 MPa for flanges exposed to `corrosive water` and can cause the occurrence of surface cracks
on the transition radius between the cylindrical part of the shaft and the flange. It has been
determined that stress values in the zone under the influence of bending stresses were bigger than
allowable values, which led to the occurrence of many cracks due to fatigue corrosion. One of
those cracks caused the failure of the shaft and of the whole turbine.

AB  - Most serious weldment failures have catastrophic consequences in terms of damage to other equipment, loss of production, and risks to worker health and safety. For the above reasons, there is a tendency to find the line between safety and disaster, and this requires a guarantee of the integrity of the welded structure even if a crack is present. The structural and mechanical heterogeneity of a welded joint affects its resistance to cracking in both the elastic and plastic regions. Therefore, it is important to define the test method and the position of the fatigue crack. The behavior of an elasto-plastic material, during stable crack growth can be described by the J-Δa diagram. As the crack propagates, a point on the curve is defined, which represents the critical value of the J-integral. The aim of this experiment is to determine JIC value and the procedure is reflected in the determination of the R-curve, i.e., the J‒Δa curve, which consists of the value of the J-integral for uniform crack increments Δa. In this paper, precracked SEN(B) specimens with the fatigue crack positioned in the weld metal (WM) were tested according to standard ASTM E1820 at room temperature (RT), -20 °C and -30 °C.

AB  - Fracture mechanics, as a scientific discipline dealing with the study of cracks in welded structures, has defined parameters and introduced new test methods in order to better determine the tendency to crack growth, critical conditions for rapid fracture development, material resistance to rapid crack propagation and better definition of other parameters for assessing the behaviour of the material and the safety of the structure in the presence of cracks. In this paper, the focus is on determination of the parameter of elastic-plastic mechanics of J-integral, more precisely, on examination of the critical value of J-integral (JIc) of the welded joint of HSLA steel. The position of the tip of the fatigue crack and the properties of the region where fracture propagation occurs are main indicators of influence of the heterogeneity of the NN-70 welded structure and mechanical properties. Resistance to cracking in the welded joint shows that the heterogeneity has a major impact on the resistance to crack initiation and propagation, in elastic as well as in the plastic region.

AB  - During the MoDeCo2000 scientific and research project on mortars used in the territory of the Roman Danube Limes in Serbia, the biggest challenge was the quest for the provenance of raw materials. The area where Viminacium, the largest city in the province of Moesia Superior developed, with millennial continuity of land use and settlement, was selected as research case study and is presented in this research. People throughout history have always used what they had at hand, and the building remains were not only reused but also recycled for new constructions. Thus, the building material of Roman Viminacium has survived in the landscape through the in situ preserved remains of Roman buildings, as well as in the structures from the later periods, up to today. To the best of our knowledge, the use of natural sediments baked during the self-combustion or combustion of underneath layers (coal in our case) for the purpose of construction was extremely rare in the Roman Empire. In this study, we follow the presence of this type of material precisely in Viminacium construction, naming it natural brick, while focusing on its potential use in lime mortars whose production was perfected in the Roman period and has never been surpassed afterward. Archaeological contexts in which this material was found have been studied, along with simultaneous work in the laboratory and in the field during the research and experimental use of the natural brick in lime mortars. We sought to determine whether this material could have been recognised by Romans in Viminacium as a potential valuable pozzolanic component of mortar, along with or instead of fired brick, being locally available and recyclable. The final confirmation of its pozzolanic features and later discussion open completely new directions for the future research of Viminacium lime mortars.

AB  - A diversity of factors, led by lithology, weathering, and erosion processes, plays a significant role in the formation and future of badland terrains. Then on previous observations it can be concluded that surface flow processes are the first trigger of erosion and that intense soil erosion combined with rapid and deep weathering are tightly connected to high erosion rates.

Since climate change presents a global issue that gains increasing attention and due to the complexity of the interactions and processes that are a part of general badlands origin and evolution, a weathering experiment on badland sediments from China was conducted. Explaining temporal changes, the impact of different precipitation types and its durations of exposure on sediments during weathering processes, as well as its impact on leachate ions behaviour are the aims behind this experiment.

Red clayey siltstone and mudstone badland sediments selected for the laboratory experiment were organized in four sets that included three different samples, making a total of 12 treated samples. Based on field climate data, in laboratory conditions samples were exposed to rain, acid rain, snow, and acid snow through fifteen daily cycles. Leachate was collected after each cycle and its volume, pH, electrical conductivity (EC), and ion concentrations were measured and analysed from the leachate. Changes occurring on the surface of the sample were observed through photographs taken at the end of each cycle.
Based on obtained results it can be said that the main differences occur when comparing rain and snow treatments generally. Temporal, cyclic changes were, to a certain extent, noticed through sediment decay. More importantly, durations of sediment exposure to precipitation proved to be crucial for weathering processes of tested siltstones and mudstones, having exclusion and ionic forces - ion exchange chromatography as dominant chemical processes.

AB  - The main objective of this study was to analyze the capacity of Cedrus atlantica (Endl.) Manetti ex Carrière 1855 to accumulate macro- and microelements in order to assess the environmental status. The element concentrations were measured using X-ray Fluorescence (XRF) analysis. The obtained pH values in this study show that the urban soils are neutral to slightly alkaline with low OM content. Macroelements with the highest mean concentrations in soil are Si, Al, Fe, K, Mg, and Ca. The ratio > 2 was determined for mean concentrations of Ca in the soil and Mg in needles from the Zvezdara forest, and for mean concentrations of Cl, Ti, and Fe in needles from the Byford’s forest in relation to the reference site. The accumulation pattern of the macroelements based on the Biological Concentration Factor (BCF) values > 1 for needles is for P, S, Cl, and Ca. Microelements with the highest mean values in soil are Ba, Zr, Ce, Cr, Zn, Rb, Sr, V, and La. Microelements with the highest mean values in Atlas cedar needles are Ce, La, Ba, and Cs. The ratio > 2 was determined for Cr and V concentrations in the needles from the Byford’s and Zvezdara forests and for Cu concentrations in needles from the Byford’s forest in relation to the reference site. The accumulation pattern of the microelements based on the BCF for needles is higher for I, Cs, Mo, Ag, Cd, In, Sn, Sb, and Tl. Since differences in the concentrations of macro- and microelements in the urban areas and the reference site can be identified C. atlantica can be recommended for assessing the environmental status.

abstract = "The main objective of this study was to analyze the capacity of Cedrus atlantica (Endl.) Manetti ex Carrière 1855 to accumulate macro- and microelements in order to assess the environmental status. The element concentrations were measured using X-ray Fluorescence (XRF) analysis. The obtained pH values in this study show that the urban soils are neutral to slightly alkaline with low OM content. Macroelements with the highest mean concentrations in soil are Si, Al, Fe, K, Mg, and Ca. The ratio > 2 was determined for mean concentrations of Ca in the soil and Mg in needles from the Zvezdara forest, and for mean concentrations of Cl, Ti, and Fe in needles from the Byford’s forest in relation to the reference site. The accumulation pattern of the macroelements based on the Biological Concentration Factor (BCF) values > 1 for needles is for P, S, Cl, and Ca. Microelements with the highest mean values in soil are Ba, Zr, Ce, Cr, Zn, Rb, Sr, V, and La. Microelements with the highest mean values in Atlas cedar needles are Ce, La, Ba, and Cs. The ratio > 2 was determined for Cr and V concentrations in the needles from the Byford’s and Zvezdara forests and for Cu concentrations in needles from the Byford’s forest in relation to the reference site. The accumulation pattern of the microelements based on the BCF for needles is higher for I, Cs, Mo, Ag, Cd, In, Sn, Sb, and Tl. Since differences in the concentrations of macro- and microelements in the urban areas and the reference site can be identified C. atlantica can be recommended for assessing the environmental status.",

AB  - The quality and vitality of cities largely depend on the design, management, and maintenance of green areas, including urban protected areas (UPAs), since they provide multiple benefits for the city. Due to urbanization and higher anthropogenic pressure, green areas are decreasing which directly affects natural habitats and biodiversity. This study aims to assess soil and vegetation chemical status in UPAs in the city of Belgrade, Serbia, and to understand how their distance from pollution hotspots affects soil and vegetation quality. Additionally, this paper considers the inclusion of soil and vegetation conditions in the urban protected areas management as a basis for introducing a connectivity approach to expand green infrastructure throughout the city. Chemical properties, the content of nutrients (C, N, P, and K), and microelements (Cr, Co, Ni, Cu, Zn, As, Cd, Sn, Pb, Zr, U, and Th) in soil and conifer needles were analyzed. Results showed that the distance of pollution hotspots does not affect nutrient and microelements concentrations in soil, i.e., they do not vary significantly between sites and do not exceed remediation intervention values. However, the microelements status of vegetation is affected since Cr, Cu, Zn, Sn, and Pb are higher in needles from trees from the city center. The state of soil and plant composition supports the establishment of a network of green corridors and should become a part of management strategies, thus helping biodiversity protection, climate change mitigation, and human well-being in the cities.

A SCC prepared with Portland cement, river sand, and limestone filler was used as a reference sample. Additional experimental self-compacting concretes with different types of fine aggregates, fillers, and special additives for increasing freeze-thaw resistance were prepared and optimized. The correlation between mix design, i.e., percentage of barite sand and additives, and properties of fresh SCC (slump-flow test, V-funnel test, and L-box test), as well as properties of hardened SCC (compressive strengths), were investigated and discussed.

AB  - During earthquakes that exceed the designed level of the structure, the structure gets damaged. Here, the structure-foundation-soil is considered as a system, and the effect of the soil on the piles can be replaced by nonlinear p-y curves. Work on this topic began as early as 1957, based on the analogy between the triaxial test and the form of soil failure, and during the 1970’s, a number of researchers made significant progress in the development of appropriate models for different types of soil. Eurocode 8 pays special attention to the selection of earthquakes as a set of accelerograms. For areas within a radius of several hundred kilometers from central Romania and its southern part, the Vrancea hypocenter has a significant influence. In North Serbia and its surroundings, other sources of earthquakes are also possible, but when choosing accelerogram, the response spectra of several Vrancea records should also be used. The SSI model itself, where the soil is replaced by p-y curves, even though it might look complicated, it is significantly simpler and leads to faster results than integral 3D models. By using adequate soil parameters, fairly reliable data can be obtained on the degree and distribution of damage to the SSI system, like plastic hinges. In soil models used for clean sand, the curves used seem significantly more reliable than clayey ones, but here too caution is needed because the degree of compaction (relative density) has a significant effect, and the way of determining it is still not reliable.

AB  - The paper shows the comparative analysis of behavior and bearing capacity of piles examined using the Dynamic Load Test (DLT) according to Static Load Test (SLT) results. The pile testing methodology is based on the existing ASTM standards and experiences of the authors of the paper. The pile tests were carried out using counterweights, reactive system, dynamic testing equipment, hardware and software for SLT and DLT. The data obtained by testing were statis-tically processed, and also a regression analysis of the linear function was conducted, resulting in the creation of the model for the change of mobilized static bearing capacity from DLT according to SLT. In addition, a procedure for correcting the solution of mobilized static bearing capacity from DLT according to SLT, is made by observing provisions of standard EN 1997-1:2004, so the average deviation of solutions from DLT according to SLT is reduced. Apart from that, through iterations, the value of correlation factor ξ5 is determined, taking into consideration solutions presented by SLT and DLT of piles of the real structures.

AB  - The application of dispersive soil can result in various types of damage, and even the collapse of embanked build-ings if it is not identified. Dispersive soils cannot be uniquely identified by visual identification in the field, or by usual standard methods used for soil identification in the geo-mechanical laboratory. The paper presents the results of laboratory geomechanical tests aimed at identifying and classifying erodible dispersive fine-grained soil. The tests were carried out using the crumb test, the double hydrometer test (SCS), and the pinhole test on samples: sandy clay embankment dams of ‘Rovni’, loess from different locations (Zemun, Novi Beograd, Titel, Kelebija, Srbobran, Slanka-men, Ruma, Mali Iđoš) and kaolinite sandy clay deposits Grabež - Aranđelovac. The possibility of improving disper-sive soil by adding fly ash was also analyzed. Pinhole tests on dispersive soil samples with the addition of 10, 30 and 50 % ash showed that there was a decrease in dispersivity of natural soil for one to two dispersion classes.

AB  - The fire reaction represents the behavior of materials during a fire event, i.e., how much the material contributes to the fire development. The importance of determining the fire reaction class stems from the need to provide sufficient time for the individuals inside a building to evacuate safely in the event of a fire. The fire reaction class is determined through a series of tests, depending on the material, with the most significant test in this group being the SBI (Single Burning Item) test. The paper describes the preparation method of test samples, the testing procedure itself, as well as the output data used for determination of the fire resistance class for tested material. According to the SRPS EN 13823 standard, a sample of a multilayered facade system with mineral wool was tested. The testing process itself, as well as the processed results, are stated in the conclusionof the study.

The paper describes the preparation method of test samples, the testing procedure itself, as well as the output data used for determination of the fire resistance class for tested material. According to the SRPS EN 13823 standard, a sample of a multilayered facade system with mineral wool was tested. The testing process itself, as well as the processed results, are stated in the conclusionof the study.",

AB  - An extremely rare carbonate breccia in the Ropočevo area (southern outskirts of Belgrade, near Avala Mt., Central Serbia), provides a clue on the probable mechanism of both its paleokarstification and a tectonic relationship with lithospheric-scale compressional events which have occurred along the latest Jurassic Neotethyan Vardar Ocean margin. Outcropping as a well-lithified block, “Ropočevo breccia” exposes an abundance of large angular, boulder-size clasts composed of recrystallized limestone. It has been used for decorative purposes in the near past. The famous decorative stone “Ropočevo breccia” represents an isolated olistolith-like carbonate block engulfed by the Upper Cretaceous Vardar Zone s.s. turbidites. In the Ropočevo area, two penecontemporaneous turbidite systems are separated by the Alpine west-vergent thrust. However, the “Ropočevo breccia” is related to neither the underlying Lower Cretaceous- nor overlaying Upper Cretaceous turbidites. Such a regional-geological relationship indicates a presence of a pre-Upper Cretaceous tectonic exhumation event, followed by the rather short subaerial paleokarst episode. The suggested paleokarst episode is characterized by the absence of progressive abrasion and of visible roundness of the considerably larger carbonate clasts. The regional geological constraints on the investigated “Ropočevo breccia” show that the isolated “olistolith” is a breccia formed by the end of Berriasian from the clasts formed in a collapsed cave within the primary carbonate sequence of the (latest Tithonian-)Berriasian age. The proposed interpretation is in line with the “Basal unit” of the Lower Cretaceous “Paraflysch” belonging to the well-hidden basal sequence of the East Vardar Zone of Central Serbia. Moreover, the available aeromagnetic data of the Avala Mt./Ripanj-Ropočevo-Kosmaj Mt. sector, corroborate a deep-settled suture underneath the investigated segment of the Vardar Ocean. The results further show that a short tectonic uplift and karstification episode occurred in connection with the compressional interruption, affecting the lithospheric-scale contact between formerly descending and overriding plates. Thus, the short regional-scale lowermost Cretaceous uplift and karstification episode was likely induced by the closure of the Neotethyan Vardar Ocean. This latest Jurassic-earliest Cretaceous collisional event produced a short compressional episode, lifting up the investigated segment of the overriding East Vardar Zone.

AB  - The paper shows the influence of steel fibers obtained from steel wire separated in the recycling process of waste car tires on the properties of concrete. The reference concrete was prepared, as well as concretes with the addition of steel fibers, which were varied in contents at 20 kg/m3 and 40 kg/m3. The slump test of fresh concrete was performed using the Webe method, where it was established that with an increase in the amount of fibers, concretes with a stiffer consistency are obtained. Concrete beams were tested for strength during flexure tension (limit of proportionality (LOP) and residual flexural strength).
Can be concluded that the residual flexure strength greater than 1.5 MPa at a CMOD of 0.5 mm is already achieved with the addition of 20 kg of fibers per m3 of concrete, while both conditions for the residual bending strengths are satisfied with the addition of 40 kg of fibers per m3 of concrete and that they amount to 2.4 MPa at a CMOD of 0.5 mm and 1.4 MPa at a CMOD of 3.5 mm.

AB  - The paper presents the influence of the use of different types of fibers on the properties of concrete. All concrete samples were made  with  same component materials and compositions, except for the amount of fibers, which was varied. After hardening, the concrete samples were tested for compressive strength, tensile splitting strength and water penetration depth under pressure. Based on the test results, depending on the type, shape, amount and arrangement of fibers, the tensile and compressive strength values as well as the depth of water penetration under pressure were analyzed. Based on the tests performed, the best mechanical properties were achieved with the use of "Dramix 3D" steel fibers.

AB  - The impacts of nano-silica addition, steel micro-reinforcement, and aggregate type on the mechanical properties and durability of ultra-high-performance concrete (UHPC) were studied. As aggregates, quartz and barite were used. The amounts of steel fibers and nano-silica were alternated. Six concrete mixes were produced with quartz sand, and the remaining six concrete mixes were designed with barite sand. Fibers made about 3-5% of the concrete composition’s mass. In a 2-5% concentration, nano-silica was used as a cement replacement. The inclusion of nano-silica significantly boosted the compressive strength of UHPC. The compressive and flexural strengths were also positively impacted by fiber supplementation ranging from 3% to 5%. The amount of fiber utilized proved to be more influential than the aggregate used. The UHPC concrete's durability was increased as all samples were highly resistant to freezing and thawing cycles. UHPC designed with barite aggregate demonstrated good X and gamma ray absorption at energies below 300 keV.
