摘要
文章以某带穿层柱框架结构商业建筑为例,通过对该结构进行多遇地震下的弹性计算和罕遇地震下的弹塑性分析,并结合大震推覆计算分析了结构整体和穿层柱受力性能。分析结果表明,在大震作用下,结构整体及穿层柱具有较好的承载和变形能力,能够达到期望的性能指标。抗震性能分析找出了抗震薄弱构件以指导结构设计,可供类似工程参考。
The frame structure with skip-floor column in a commercial building is taken as an example, and the whole structure and the skip-floor cohmm force performance are analyzed through the elastic calculation under frequent earthquake, the elastic-plastic analysis under rare earthquake and the strong earthquake seismic calculatioru The analysis results show that the whole structure and the skip-floor column have good carrying ca- pacity and deformation capacity under the strong earthquake, which are up to the desired performance indices. The seismic analysis reveals the weak seismic member, which is helpful for guiding the structural design and providing reference for similar projects.
