摘要

This paper presents the methodology of the reliability analysis of the fire resistance of the steel structure of the cable way in NPP. The elastic and plastic solution of the steel structure under fire loads is discussed. The deterministic and probability analysis of the fire resistance of the steel structures are considered. The executed fire resistance analysis of the steel structures is investigated as the influence of temperature, permanent and variable loads. A Response Surface Method (RSM) for the nonlinear analysis of the fire structure reliability was used on program ANSYS. The advantages and disadvantages of the deterministic and probabilistic analysis of the fire safety are discussed.
