摘要:
为研究门式刚架结构纵向支撑体系的抗震性能,采用有限元软件ANSYS对《门式刚架轻型房屋钢结构》(02SG518-1)中的GJ18-1C、GJ24-1C、GJ30-1C、GJ36-1C四个门式刚架在不同工况纵向地震作用下的性能进行了动力弹塑性时程分析.分析结果表明:门式刚架结构的纵向地震作用较小,即使在罕遇地震阶段,纵向地震作用引起的结构内力仍较小,柱顶侧移也远小于规程要求,表明按现行规程设计的门式刚架完全能满足结构纵向变形要求,具有优良的纵向抗震性能
Abstract:
In order to study the longitudinal seismic behavior of one-story single-span portal frame structure, a finite element analysis of portal frame structure was performed to simulate the overall elasto-plastic time-history process with FEM program ANSYS. The type of portal frame included GJ18-1C,GJ24-1C,GJ30-1C,GJ36-1C,in portal frame light steel structure housing atlas(02SG518-1), respectively. The study reveals that the longitudinal seismic effect of portal frame structure was small,and even at rare earthquake stage, the maximum displacement at the top of column is far less than required by the code, and the portal frame designed according to the current regulations can satisfy vertical deformation requirements
