叠合板式剪力墙竖向拼缝构造措施性能分析

Performance Analysis of Vertical Joint Construction Measures of Superimposed Slab Shear Wall

为研究竖向拼缝构造措施方式对叠合板式剪力墙性能的影响,应用Abaqus有限元软件对整体式叠合板剪力墙和3组竖向拼缝处采用不同构造措施的叠合板式剪力墙进行有限元分析,研究其裂缝分布、破坏形态、滞回曲线、骨架曲线及刚度退化曲线等抗震性能.结果表明:3组竖向拼缝处采用不同构造措施的叠合板式剪力墙与整体式叠合板式剪力墙抗震性能基本相同,通过在竖向拼缝处设置相应的构造措施能有效保证叠合板式剪力墙的整体性.分析结果可为叠合板式剪力墙竖向拼缝连接的研究提供参考依据.

In order to study the influence of vertical joint construction measures on the performance of superimposed plate shear wall,Abaqus finite element software was used to analyze the integral superimposed plate shear wall and three groups of superimposed plate shear walls with different structural measures at the vertical joint,and the seismic performance of crack distribution,failure form,hysteretic curve,skeleton curve and stiffness degradation curve were studied.The results show that the seismic performance of three groups of superimposed shear walls with different structural measures is basically the same as that of integral superimposed shear walls,and the integrity of superimposed shear walls can be effectively guaranteed by setting corresponding structural measures at the vertical joints.The analysis results can provide reference for the research of vertical joint connection of superimposed plate shear wall.
