【 摘 要 】

Mechanical characterization of steel frame structure after fire are analyzed based on fire dynamics, heat transfer theory, structural mechanics, and finite element theory. We study the temperature characteristics and mechanical properties of steel frame structure under different fire locations and propose a safety evaluation method. We also analyze damage level of main frame components, maximum temperature of fire, thermal characteristics of frame components, firing duration, etc. to provide useful information for fire resistance design of the steel frame structure and post-disaster safety evaluation.
