AB  - Testing the clay hollow-brick masonry non-load-bearing wall helps us to understand the behaviour of this type of wall during a fire. It is important to know the fire resistance of hollow brick walls so that we can prevent the fire from spreading to other rooms. In this paper, the experimental analysis of fire resistance of non-load-bearing wall with dimensions 3000 mm x 3000 mm thickness 200 mm were presented. The wall was made from clay hollow-brick masonry blocks with dimensions 500 mm x 200 mm x 249 mm (L x D x H) with mortar on both side of wall of thickness 15 mm. The wall was exposed to a standard fire test according to SRPS EN 1363-1:2014. The temperatures on the unexposed side of the wall were measured in thirteen positions with thermocouples (K – type) according to the national standard SRPS EN 1364-1: 2014, and at the junction between mortar and clay hollow-brick. Deflection of the wall in five places was measured also. Obtained results depending on the time of reaching the critical temperature during the fire test were presented.

AB  - The unsteady heat conduction in composite planar structure, with arbitrary number of layers, using analytical approach based on Greeds Functions (GF) is analyzed. The analytical solution for spatial and temporal temperature distribution is evaluated in the general form and expressed in the terms of the convolution integrals. The GF are employed in the novel approach for calculation of Thermal Response Factors (TRF) with arbitrary shape functions for unsteady heat conduction in composite planar structure. The two pairs of TRF for spatial and temporal distribution of the temperature and the thermal flux are obtained. The whole analysis is performed in the time domain. A numerical scheme for efficient evaluation of convolution integral suitable for practical application in the case of the long term measurements with lower sampling rates is developed. The in-situ measurements of inside and outside surface temperatures and outside heat flux for a building wall under real dynamical environmental conditions during the period of then days are used for validation of the presented results and to demonstrate the possible practical application. Using developed approach and recorded surface temperatures as inputs the temporal and spatial distributions of the temperature and the thermal flux are obtained. These results are compared with experimental data and numerical simulations obtained by the Finite Volume Method (FVM).

AB  - In this paper a comparative analysis of thermal behavior of six partition walls with different
thicknesses were presented. The walls were dimensions 3000 mm x 3000 mm made from autoclaved
aerated concrete blocks with dimensions 625 mm x 200 mm and thicknesses 50 mm, 75 mm, 100 mm,
120 mm, 150 mm and 250 mm. All walls were exposed to standard fire test according the standard
SRPS EN 834-1, non- combustibility test according the standard SRPS EN 1182 and surface spread of
flame test according to SRPS U.J1.060. All walls were tested to fire resistance in vertical furnace with
a data acquisition system, according to standard fire test. Standard furnace for testing construction
consist of four two step burners in liquid fuel type of 296
kW manufactured by ECO FLAM. Two transmitters of differential pressure type 6321 manufactured
by TESTO (Germany), with range 100 Pa installed inside the furnace were used for pressure
measurement. Inside the furnace the temperature on six places with thermocouple type K were
measures. The measure ranges of thermocouple type K were -2700C to 13720C. The temperatures on
unexposed fire side were measured in nine places with thermocouple type T with measure ranges -
2700C to 4000C of according the national standard SRPS U.J1.090. The obtained temperature results
depending of the time of reaching the critical temperature were presented for each wall thicknesses.
The five identical cylindrical samples with high 50 mm and diameter 45 mm for non-combustibility
test has been used. All samples have been tested in standard furnace for non-combustibility test. The
average temperature in furnace and specimens were presented. Surface spread of flame testing is
carried out according to standard SRPS U.J1.060, if the coating material is based on organic or mixed
materials. The samples for these test are with dimensions 900 x 230 mm.

outdoor measurements were carried out simultaneously during the period of 1 month in
a dwelling of residential building located in Belgrade, Serbia. The data were used to
calculate the thermal transmittance of the wall according Standard ISO 9869-1:2014.
The U-value obtained from the experimental data and those calculated in steady-state
temperature regime are compared. Criteria for the data that have to be met in order to
get accurate U-value are discussed.

estimation by filtering an experimentally collected data. The experimental data were
obtained in simultaneous measurements of inside and outside temperatures variations
during the period of 3 months of a building located in Belgrade, Serbia. The TTF
estimation is based on Wiener filtering technique for the dynamic systems with finite
impulse response (FIR). TTF is derivate in time and complex domain and the correctness
of the acquired transfer function is tested on the new input data set. The estimated TTF in
complex domain is used to get decrement factor (DF) and time lag (TL) between the
temperatures.

AB  - In this paper, the results of numerical simulation of 2D non-stationary
temperature fields in commonly used composite structural members made of steel and
concrete in fire conditions were presented. Simulation is based on the model which
includes temperature dependence of physical parameters of materials, specific heat and
thermal conductivity. Analysis of composite structural members comprises determination
of a heat flux field which additionally facilitates understanding of region and geometry of
heat flow, thus enhancing fire protection design. Initial temperature distribution is
adopted as uniform, according to Eurocode. Fire conditions were according to ISO 834.
The FEM computations for different protection scenario and protective materials for
partially encased I section - are conducted in ABAQUS. Obtained results can be used in
cost optimization of fire protection measures.

AB  - Fractal geometry theory implied in a composite surface topographic analysis as a means of explanation of the structural characteristics has hardly been reported so far. This paper proposes a new method of roughness peaks curvature radii calculation and its application to the refractory composite surface tribological analysis. Fractal geometry method is introduced via calculation of asperity radius, by introducing a fractal concept of curvature radii of surfaces, depending on the observation scale and also numerically depending on horizontal lines intercepted by the investigated profile. The dependence of the calculated radii on the fractal geometry of the studied curves was established and the notion of peak was mathematically formulated. The efficiency of the method was tested by simulations of fractal curves described by Brownian motions. Microstructural investigations were carried out using a scanning electron microscope. The correlation between microstructure and properties of the investigated refractory composite, based on fractal geometry and contact surface probability, has been developed. Using the fractals of the contact surfaces of grains, a reconstruction of microstructure configuration, as grain shapes or inter-granular contacts, has been successfully performed. Obtained results indicated that fractal analysis of contact surfaces of different shapes was very important for the prognosis of refractory composite properties and behavior. The morphology of composite grains and surfaces highlighted the validity of developing new structure analytical methods based on different grain shape geometries. The novel approach to the investigation of refractory composite characteristics was successfully conducted, as a result introducing fractal identification as a means of evaluating and predicting material performances.
