摘要
高温下钢框架试验中外荷载大小的选定对试验结果有着重要的影响。本文应用火灾科学和相关结构理论,对钢框架在高温下的力学特征进行分析,提出一种基于试验对比的反演计算法;该方法利用相关规范来反推不同温度下的极限荷载,并分析了钢框架主要构件在火灾下的受力特性;通过数值分析验证了两层两跨钢框架极限荷载理论计算结果,为以后进行相关钢框架试验研究提供参考依据。
Selection of external loads has an important effect on the test results of full-scaled steel frame under fire. In this paper,an inversion method based on the fire science and structural mechanics is proposed to analyze the mechanical characteristics of the steel structure under high temperature. The ultimate loads under different temperature are calculated,all the calculation results are proved by date analysis. This paper lays the groundwork for further relative research.
