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.
