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.

AB  - The unsteady heat conduction in composite planar structure, with arbitrary number of layers, using analytical approach based on Green's 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, 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.
