The Current Situation and Development of Fire Resistance Design for Steel Structures in China

A review of the current situation and development of fire safety design for steel structures in China is given in this paper.Several codes and specifications used for fire safety design in China are introduced, and the present design methods are summarized.Then some research achievements on the behavior of steel structures at elevated temperature are presented.The achievements include material properties of steel at high temperatures, finite element theoretical analysis and experimental research on steel structures and structural members, high-temperature behavior of beam-to-column joints, fire resistance of composite structures and structural members, and etc.From all of the content, the conclusion is drawn that the fire safety researches of steel structures need to be further carried out both theoretically and experimentally, although obvious works have been achieved.
