Loading-bearing Capacity Method for Structural Fire Safety Design - A Case Study

Abstract

Calculation methods have been developed for application to advanced fire-resistance design. The loading-bearing capacity method involves the performance of a structural analysis for a fire situation using the computer-based finite element method, and checks the loading-bearing capacity of the structure in a fire ultimate limit state. There is a case of a steel roof grid structure fire-resistant assessment to illustrate the basic steps in the loading-bearing capacity method for structural fire safety design. A detailed finite element analysis of a space truss with a credible design fire was carried out to determine the deflections and forces in the space truss, and checked by the fire ultimate limit state. The present data and analysis demonstrate that the loading-bearing capacity method is sufficient for fire safety design.
