摘　　要：为了保证双面叠合剪力墙结构体系应用的安全性和可靠性,建立由上、下两层墙体和中间楼板组成的双面叠合剪力墙构件模型及现浇对比模型,并进行基于Abaqus软件的数值模拟分析。研究内容包括双面叠合剪力墙整体位移、混凝土及钢筋的应力分布、最大承载力、耗能能力。结果表明,在小震弹性阶段,带楼板的双面叠合墙板与现浇对比试件的刚度一致;在大震作用下,带楼板的双面叠合墙板的耗能能力低于现浇对比试件,但总体耗能能力都较好。因此,合理设计下的双面叠合剪力墙结构具有良好的抗震性能。In order to ensure the safety and reliability of double-sided superimposed shear wall structure system,a two-sided superimposed shear wall component model composed of upper and lower walls and middle floor as well as a cast-in-place comparison model are established,and numerical simulation analysis is carried out based on Abaqus software.The research contents include the whole displacement of double-sided superimposed shear wall,stress distribution of concrete and rebar,maximum bearing capacity and energy dissipation capacity.The results show that the stiffness of double-sided laminated wall panels with floor slabs is the same as that of cast-in-place comparison specimens in small seismic elastic stage.Under the action of large earthquake,the energy dissipation capacity of double-sided laminated wall panels with floor slabs is lower than that of cast-in-place comparison specimens,but the overall energy dissipation capacity is better.Therefore,the two-sided superimposed shear wall structure with reasonable design has good seismic performance.
