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.

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.

Also presented are the problems with the installations of buildings with a roof terrace, such as downpipe verticals that are extending through the building, or installations of water supply and sewerage that run through the technical floor at ground level. An approximate analysis of the hydrodynamic impact is presented. The analogy of the effects of caverns in sandy soil with lateral soil expansion during liquefaction was also used. Given the change in climatic conditions, it is necessary in some cases to analyze the influence of atmospheric conditions in the soil-structure interaction. The advantage of buildings built in the frame IMS system (Žeželj) in seismically active areas was also indicated. These buildings are also more resistant to problems that may arise later in construction of deep foundations.

AB  - The paper presents the comparative analysis of several piles for different pier locations of a bridge by employing in-situ deep foundations tests and in-situ soil tests. The focus of the paper is on the
presentation of the reliability of solutions obtained using the Dynamic Load Test (DLT) for in-situ
tests of the bearing capacity of deep foundations – piles. The DLT test was conducted in two stages:
in-situ DLT of piles and pile bearing capacity analysis using the wave theory and the method of
characteristics. The signals of upward traveling force waves, obtained by in-situ DLT of piles were
signal matched with the signals of the numerical nonlinear model of the dynamic pile-soil interaction.
The results of DLT of pile bearing capacity are presented as componential values (regarding the pile
base and the pile shaft) and as a cumulative value (total bearing capacity), so that the comparison of
DLT and pressuremeter test (PMT) was conducted both according to componential and cumulative
bearing capacities. Since it is not possible to strictly conduct DLT and PMT for the same settlement
level, it is not possible to directly compare the bearing capacity, however the comparison was
performed taking into account the bearing capacities from PMTs according to Eurocode 7. DLTs
provided bearing capacities which correlate well with the PMTs results. Also, DLTs determined the
corresponding elastoplastic settlement for the designed resistance of piles, which is very useful to the designers in the analysis of serviceability (settlement) of both the pier locations and of the entire bridge.

AB  - Bipedal models for walkers, originally developed in the research field of biomechanics,
have been identified as potential candidates for modelling pedestrians in structural engineering
applications. These models provide insight into both the kinetics and kinematics of walking locomotion and are considered to have a significant potential to improve the vibration serviceability
assessment of civil engineering structures. Despite this notion, the ability of the bipedal models to
represent the key features of the walking gait and natural variability within the pedestrian population are still under-researched. This paper critically evaluates the performance of two bipedal models with rigid legs to realistically both reproduce key features of an individual pedestrian’s walking gait and represent a wide range of individuals. The evaluation is performed for walking on a rigid, rather than vibrating, structure due to the availability of experimental data and expectation that successful modelling on rigid surfaces is a necessary condition for progressing towards modelling on the vibrating structures. Ready-to-use equations are provided and the ability of the models to represent the kinematics and kinetics of individual pedestrians as well as the inter-subject variability typical of the human population is critically evaluated. It was found that the two models could generate realistic combinations of the gait parameters and their correlations, but are less successful in reproducing genuine kinetic and kinematics profiles.

AB  - This paper deals with the aspects of vibration analysis of 3D numerical water tower models with the explicitly generated 3D finite element (FE) solid fluid model that simulates the fluid-structure interaction (FSI). The development and implementation of the 3D FE solid fluid model in modelling and analysing the system response is extremely important, both in terms of determining the impulsive and convective hydrodynamic pressure, and in terms of overall sizing of the water tower. Vibration of the water tower is calculated based on the analysis of its eigenvibrations, analysis of eigenvibrations occurring when charging and discharging the water tower reservoir (SFA - Staged Fluid Analysis), Steady-State Analysis (SSA) in the frequency domain and the analysis of the system response in the time domain (THA - Time History Analysis), followed by the transformation of the frequency domain response using the Fast Fourier Transform (FFT). The analysis of eigenvalues using the Ritz vectors (Ritz analysis) and the Power Spectral Density Analysis (PSDA) are carried out as the means of additional control and with the purpose of identifying vibration periods. The system's stiffness matrix and mass matrix are corrected using the 3D FE solid fluid model for analysing the water tower vibrations. Effects of the system's increasing vibration period are determined for the partially charged reinforced concrete (RC) water tower reservoir, given the strong action of the fluid mass that is excited for convective hydrodynamic action (sloshing) due to the water tower dimensions and the amount of fluid contained in the reservoir in this case.

AB  - This paper formulates a mathematical model using the extrapolation of load-settlement curves with a rational function for analyzing the capacity of piles obtained from the static load test (SLT). In preliminary analyses, the extrapolation was based on the application of a number of mathematical functions that were gradually eliminated by iterative selection and filtering. The solution was obtained by extrapolation with a rational function. Using a rational function in the extrapolation of the load-settlement curve, a clearly identifiable part is obtained in which the asymptote is vertical, indicating the reached limit state of capacity in the soil and/or in the pile. The probabilistic analysis showed that no unique value for pile capacity was obtained, and that the spectrum of capacity values depends on the probability of occurrence of the corresponding event.

Klasifikacija je sprovedena po tipovima testova u kojima su jasno definisani: tok ispitivanja šipova, metode analize i obrade rezultata ispitivanja. Pored osnovne podele testova ispitivanja šipova na testove integriteta i testove nosivosti, dodatno je definisana i grupa testova kontrole bušotine kod bušenih šipova, s obzirom na to što je za pravilno formiranje bušotine, kada je reč o bušenim šipovima, neophodno prethodno ispuniti određene kvalitativno- kvantitativne kriterijume. Ovako prikazane metodologija i klasifikacija ispitivanja integriteta i nosivosti šipova prvenstveno služe za edukativne svrhe inženjera građevine i geotehnike koji se bave ovom problematikom, da dodatno donese novine na ovom polju ispitivanja i da dodatno pojasne sve elemente ispitivanja, budući da se u praksi vrlo često susreću protivrečna mišljenja i nesuglasice oko detalja ispitivanja.
AB  - The paper presents the methodology and classification of pile integrity and load testing, in compliance with current foreign standards, as well as our own defined segments of standard improvement and our own definitions of certain key elements. The classification has been conducted according to the test types which clearly define the pile testing process, analysis methods, and test results processing. Beside the basic division of pile testing to integrity tests and load tests, there is also an additionally defined group of shaft control tests in the case of bored piles, since for the proper shaft formation, when it comes to bored piles, certain qualitative-quantitative criteria must be fulfilled beforehand. Presented in this way, the methodology and classification of pile integrity and load tests serves, primarily, an educational purpose for civil and geotechnics engineers who deal with this issue, to additionally introduce innovations in this field of testing and clarify all the elements of the testing since contradictory opinions and disagreements regarding the testing details are quite common in practice.

AB  - U radu je prikazana procedura evaluacije seizmičkih performansi interakcije šip-tlo inkrementalnom nelinearnom dinamičkom analizom (INDA -Incremental Nonlinear Dynamic Analysis). Ulazni signal u sistemu je tretiran preko generisanih veštačkih akcelerograma, a koji su dodatno procesirani po slojevima tla do osnovne stene. Postprocesiranje INDA analiza izvršeno je posebno za stub, a posebno za šip, tako da su konstruisane krive PGA=f(DR) u kapacitativnom domenu. Za ovako konstruisane krive određeni su performansni nivoi, a na osnovu određenih DR i PGA parametara sprovedene su regresione analize. Krive povredljivosti su konstruisane na osnovu rešenja regresione analize i teorije verovatnoće log-normalne raspodele. Takođe, konstruisane su i krive pouzdanosti na osnovu rešenja analize povredljivosti. Metodološki postupak za analizu seizmičkih performansi, prezentovan u ovom istraživanju, omogućava integrisano kvantitativno-kvalitativno razmatranje i evaluaciju kompleksne interakcije konstrukcija-tlo (SFSI -Soil-Foundation-Structure Interaction).
AB  - The purpose of this paper is to present the methodology for performance-based seismic evaluation of soil-pile-bridge pier interaction using the incremental nonlinear dynamic analysis (INDA). The system's input signal was treated through the generated artificial accelerograms which were subsequently processed by soil layers and for the bedrock. The INDA analysis was post processed separately for the pier and for the pile, so that the constructed PGA=f(DR) curves are in the capacitive domain. For these curves the authors identified the performance levels, while the regression analyses were conducted based on the specific DR and PGA parameters. Fragility curves were constructed based on the solutions of regression analysis and the probability theory of log-normal distribution. Based on the results of fragility analysis, reliability curves were also constructed. The methodological procedure for seismic performance analysis presented in this study provides an integrated quantitative-qualitative consideration and evaluation of the complex soil-foundation-structure interaction (SFSI).

AB  - Autori rada su, na osnovu analize velikog broja naučnih radova, dali prikaz sopstvene originalne sistematizacije seizmičkih analiza konstrukcija, a veliki deo njih je razvijen u poslednje dve decenije. Seizmičke analize su klasifikovane generalno u dve (četiri) grupe: linearne i nelinearne statičke analize; i linearne i nelinearne dinamičke analize. Posebno su klasifikovane analize nelinearnog seizmičkog odgovora konstrukcija, a posebno analize ciljnog pomeranja kojim se definiše odnos seizmičkog zahteva i seizmičkog odgovora. S druge strane, klasifikacija je sprovedena i u funkciji da li se nelinearan odgovor sistema dobija primenom inkrementalno-iterativnih procedura ili primenom poluiterativnih i/ili poluinkrementalnih procedura. Nelinearne dinamičke analize su klasifikovane prema konceptu matematičke formulacije, odnosno da li se zasnivaju na samo jednoj dinamičkoj analizi, većem broju dinamičkih analiza ili dobijaju rešenja u kombinaciji s drugim metodama. Primenom sprovedene sistematizacije seizmičkih analiza može se vrlo efikasno razmotriti koji tip analize je optimalan za analizu konstrukcija i koji tip analize je potrebno uzeti u obzir u fazi preliminarnih i finalnih analiza za naučna istraživanja i stručne projekte. U radu su, takođe, prikazani aspekti modeliranja prigušenja u analizi konstrukcija sistematizacijom tipova prigušenja i formiranim dijagramima tokova, a u zavisnosti od tipa primenjene analize: linearne i nelinearne, statičke i dinamičke. Sistematizacija prigušenja je sprovedena prema načinu uvođenja u proračun i to preko prigušenja materijala, prigušenja elemenata veze i prigušenja koja se direktno uvode u analize, a koje se sprovode u kapacitativnom, vremenskom i frekventnom domenu. Primenom razvijenih dijagrama tokova, u procesu kreiranja numeričkih modela konstrukcija, može se vrlo efikasno razmotriti koji tip prigušenja treba odabrati i na koji način uvesti prigušenje u analizu konstrukcija. Takođe, primenom razvijenih dijagrama tokova mogu se definisati i alternativni pristupi uvođenja prigušenja u analizu konstrukcija.
AB  - The authors of the paper, on the basis of the analysis of a large number of scientific papers, presented their original systematization of seismic analyses of structures, where a large number of them were developed during the last twenty years. Seismic analyses are generally classified into two (four) groups: Linear Static Analyses (LSA) and Nonlinear Static Analyses (NSA), and Linear Dynamic Analyses (LDA) and Nonlinear Dynamic Analyses (NDA). The analyses of nonlinear seismic structural response were classified separately from the Target Displacement Analyses (TDA) which defines the relationship of the seismic demand and seismic response. On the other hand, classification was also conducted depending on whether a nonlinear response of the system is obtained by the implementation of incremental-iterative procedures or by implementation of semi-iterative and/or semi-incremental procedures. NDA were classified according to the concept of mathematical formulation, i.e. whether they are based on only one dynamic analysis, several dynamic analyses or they are solved in combination with other methods. By implementing the conducted systematization of seismic analyses, one can efficiently consider which type of analysis is optimal for structural analysis and which type of analysis should be taken into account in the phase of preliminary and final analyses in the course of scientific research and professional projects. This paper also presents the aspects of damping modelling in structural analysis through the systematization of damping types and flowcharts, depending on the type of analysis applied: linear and nonlinear, static and dynamic. Damping has been systematized based on the way it was introduced into calculations, i.e. over material damping, link element damping and damping directly introduced into the analyses which are conducted in capacitive, time and frequency domains. In the process of creating numerical structural models, the type of damping and the way of its introduction into structural analysis can be very efficiently selected by applying the flow charts developed. By applying the developed flowcharts, alternative approaches to the introduction of damping into structural analysis can also be defined.

of analytical-numerical models for the analysis of geotechnical structures. In addition to structures
formed only from the soil, geotechnical structures also include geotechnical injections, combination
of soil and reinforced concrete (RC) elements, primary RC structures in the soil, structures from
geotextiles/geogrids/geocells and the like. In the group of geotechnical structures, where the
primary role is played by the RC structure in the soil, a specific place is taken by the issue of
analyzing the capacity and integrity of piles. There are a large number of analytical and numerical
methods developed for the purpose of determining the capacity and integrity of piles, as well as a
large number of in-situ tests of real piles constructed in the ground. Also, a series of alternatives
were developed for solving problems in the everyday engineering practice and scientific research.
Despite of this, there are a number of unresolved issues in determining the capacity and integrity of
piles, especially in case of piles in existing structures. This raises a number of questions, such as:
what method, when and for what type of piles should be used? Answers to these questions can be
found in a variety of publications, but there are a considerable number of questions to be answered in order to enhance the practice and scientific knowledge in terms of analyzing the capacity and integrity of piles, and develop new sophisticated and reliable solutions. This paper provides a summary of pile capacity and integrity tests for quick and reliable assessment and the choice of the type of test in different situations. The paper analyzes the most commonly used tests in practice, as well as tests of new generation which have been increasingly used and may replace some proven reliable tests.

AB  - A probabilistic concept for determining pile bearing capacity is presented, taking into account the variability of CPT test parameters and methodology of calculation according to the requirements of Eurocode 7 (EN 1997-1: 2004). Based on a single initial (real) CPT test, a larger number of generated (simulation) CPT tests are introduced drawn from solutions of statistics and probability theory. Research has found that the best solutions are achieved using the DA 2 design approach for n(CPT) > 10 tests. Taking into account the deterministic and probabilistic approach in the analysis of pile bearing capacity, it is found that for the DA 2 design approach, the ratio of pile bearing capacity obtained from simulation and the capacity as determined through three methods (Mazurkiewicz, Van der Veen and hyperbolic approximation) is Rcd, /Pu = 1.148. Using the reliability index, the following values of partial resistance factors are obtained: λ, s /P 1.1, λ, b /P 1.1, which also points to the DA 2 design approach.

AB  - The paper presents a multidisciplinary approach to the assessment of seismic performances based on the Performance-Based Earthquake Engineering (PBEE), taking into account the multi-criteria optimization theory in analyzing the priority methods for bridge rehabilitation/strengthening. One bridge model was subjected to nonlinear static pushover analyses (NSPA), target displacement analyses using the spectrum capacity method (CSM), vulnerability analyses, and reliability analyses, while for a damaged bridge, in addition to be considered using the above methods, was also analyzed using the VIKOR method of multi criteria optimization. Seismic performances were determined based on monitoring the system's plastification and analyzing the relevant parameters for the level of target displacement, such as target displacement, total shear force, spectral displacement, spectral acceleration, vibration period, damping and ductility. The phases of damage were considered using the probabilistic analysis of vulnerability and reliability: slight, moderate, extensive and complete, as a function of system ductility.

AB  - A multitude of existing bridges fail to meet the criteria of seismic resistance, as designed according to
inadequate regulations, which eventually led to the reduction in their resistance. This practice requires
interventions (rehabilitation or strengthening) conducted on their structure, which in turn requires
developing methods of assessment of seismic performances of existing reinforced concrete (RC)
girder bridges. Due to budget constrains it is impossible to strengthen all the bridges, so that a list of
priorities is necessary to be drawn. The rank of a specific bridge in this list is stated by the importance
of the road, age of the bridge, technical regulations according to which the bridge was designed and
the condition of vital support elements. Ranking requires conducting multi-criteria optimization. This
paper is focused on overpass, which is used to demonstrate the developed methodology.

AB  - U radu je razvijena i prikazana metodologija za analizu oštećenja objekata koji su izloženi incidentnom i seizmičkom dejstvu. Procedura se bazira na nelinearnim numeričkim analizama, uvažavajući principe projektovanja konstrukcija prema seizmičkim performansama (PBSD). Matrica krutosti za uticaje vertikalnog dejstva koristi se kao inicijalna matrica krutosti prilikom nelinearne analize kojom se simulira kolaps pojedinačnih stubova prizemlja, formirajući nekoliko mogućih scenarija. Matrica krutosti na kraju analize, kojom se simulira kolaps pojedinačnih stubova, koristi se kao inicijalna matrica krutosti prilikom nelinearne statičke pushover analize (NSPA) za bidirekciono seizmičko dejstvo (X i Y pravac). Analize ciljnog pomeranja sprovedene su prema metodi spektra kapaciteta (CSM). Procena stanja zgrade je sprovedena na osnovu proračunatih globalnih i međuspratnih driftova i razvijenog koeficijenta oštećenja. Razmatranje stanja oštećenja zgrade utvrđeno je integralnim pistupom i preko globalnih i preko međuspratnih driftova, tako da se - u zavisnosti od nivoa pomeranja za koji se driftovi određuju - dobija pouzdaniji odgovor. Primenom koeficijenta oštećenja može se dobiti veoma brz, pouzdan i dovoljno precizan odgovor kada je reč o nivou oštećenja kompletne zgrade u kapacitativnom domenu, od elastičnog, preko nelinearnog, pa sve do stanja kolapsa.
