Security Studies55Figure 6 Numerical simulation of temperature distribution by ANSYS finite element methodCONCLUSIONSIn order to predict the disruption of and damage to critical infrastructure elements it is importantto take into account the structural resistance of such elements. A structural-reliability analysisof so called accidental actions is required. For structural-reliability analysis maximum loadarising from the treat scenarios has to be set, and geometric and mechanical characteristics ofthe critical infrastructure element have to be known. The paper describes such treats in the formof extraordinary loads and the various tests conducted at the Faculty of Security Engineering.BIBLIOGRAPHYArteaga, A. “Classification of actions”.

Figure 4 Field tests – blast resistance
During the blast test pressure, strain and acceleration were measured. The measured
parameters were compared with the analytical and numerical model. The behaviour of such
blast loaded structures were described. Other tests were made by Štoller, J. and Zezulová, E. 7
Fire resistance
The last area of testing and numerical simulation to describe the resistance of various elements
was the research against the effect of fire. Fire resistance and loss of stability of
selected structural elements were done. The elements were concrete elements with various
area sections. Concrete beams with encased steel profiles (see Figure 4.)
Figure 5 Cross section of elements for fire resistance analyses
As we have already mentioned temperature distribution in a circular cross-section were
examined. The elements were exposed to fire for the duration of 120 min. Numerical simulation
was done using finite element methods in ANSYS (see Figure 6).
