摘要
分析了某二层钢结构房屋倒塌的过程与现状,指出结构设计缺陷是该钢结构房屋倒塌的主要原因。在此基础上,研究消除这些结构设计缺陷对结构性能的改善,并提出柱下梁无支承加劲肋时,梁翼缘最小厚度的计算方法及公式。
This paper analyzed the collapse procedure and present situation of a two-story steel frame,it was also pointed out that the structural collapse resulted from the improper structural design.Based on the analysis, improvements on the failure design were investigated,and the calculation method and formula of the minimum flange thickness of the steel beam supporting column without stifferner were proposed.
