Editorial: Safety and Reliability for Managing Risk, European Safety and Reliability Conference (ESREL 2006), Date: SEP 18-22, 2006 Estoril PORTUGAL, 1-3, p. 2081-2086, 2006.


This paper deals with an elastic and plastic solution of the steel frame under fire loads. The deterministic and probability analysis of the fire resistance of the steel frame is considered. The executed fire resistance analysis of the steel structures is investigated as the influence of temperature, dead loads and live loads. Deterministic analysis is carried out in accordance of EUROCODE requirements. The Simulation-Based Reliability Assessment concept (SBRA) is applied for probabilistic analysis. The MONTE CARLO simulation using AntHILL program is realized for 106 simples of input data. The stiffness analysis of the steel frame fire resistance is calculated in ANSYS. The sensitivity analysis of the various input parameters shows the significant influence of the considered loads and material properties.
