摘要
为了研究某高层建筑的抗震性能,对高层装配整体式剪力墙结构动力弹塑性时程进行分析。利用ABAQUS有限元软件,构建高层装配整体式剪力墙结构动力弹塑性材料本构关系有限元模型,模拟地震作用下高层装配整体式剪力墙结构动力时程变化情况。分析结果表明:整体剪力墙结构前6阶振型每两阶平动振型出现一个扭转,且计算结果符合规定,测试剪力墙时程位移变化结构也符合相关规定。随着地震波加载时间的增长,高层装配整体式剪力墙结构受拉损伤逐渐严重。加载至40s时,该结构的混凝土材料已经不能发挥作用,只能依靠钢筋支撑,但未出现明显坍塌,剪力墙结构受压损伤主要出现在剪力墙结构的连接位置,未出现明显受压损伤。说明该高层装配整体式剪力墙结构抗震性能良好。
In order to analyze the seismic performance of an actual high-rise building,the dynamic elastic-plastic time history of a high-rise assembled integral shear wall structure is analyzed.ABAQUS finite element software was adopted to construct a dynamic elastic-plastic material constitutive relationship finite element model for high-rise assembled integral shear wall structures and simulate the dynamic time history changes of high-rise assembled integral shear wall structures under earthquake action using finite element software.The analysis results show that the first six vibration modes of the overall shear wall structure undergo one torsion every two translational vibration modes,and the calculation results comply with the regulations.The displacement changes during the testing of the shear wall also comply with relevant regulations.With the increase of seismic wave loading time,the tensile damage of high-rise assembled integral shear wall structures gradually becomes severe.When loaded to40 seconds,the concrete material of the structure is no longer functional and can only rely on steel reinforcement support,but there is no obvious collapse.The compression damage of the shear wall structure mainly occurs at the connection position of the shear wall structure,and there is no obvious compression damage.The above results demonstrate that the high-rise assembled integral shear wall structure has good seismic performance,and this time history analysis is more effective and comprehensive.
