摘要
基于非线性有限元分析软件MSC.Marc,对一个10层新型混合装配式剪力墙结构进行了罕遇地震作用下动力弹塑性分析。分析结果表明,罕遇地震作用下,连梁应力较大,起到耗能作用;墙肢受压损伤主要出现在1层-3层墙体暗柱处,暗柱内的纵筋屈服;内外墙协同工作性能良好。新型混合装配式剪力墙结构弹塑性层间位移角满足规范要求的1/120限值要求,结构具有较好的抗震性能,满足大震不倒的性能要求。
Based on the nonlinear finite element analysis software MSC.Marc,the dynamic elastic-plastic analysis of a new 10-storey hybrid prefabricated shear wall structure under rare earthquake was carried out.The analysis results show that the stress of the coupling beams is large and plays a role in energy dissipation under the action of rare earthquakes.The compression damage of the wall mainly occurs at the structural column of the 1st to 3rd floor,and the longitudinal bars in the structural column yield.Internal and external walls work well together.The elastic-plastic drift ratio of the new hybrid assembled shear wall structure meets the 1/120 limit value of the specification,and the structure has good seismic performance,which can meet the performance requirements of non-collapse.
