Analysis of the Deformation Performance of Superimposed Wall Plane

Shear connectors connect the precast interior walls to the cast-in-place exterior walls in a stacked shear wall, and the interface is the weak side of the structure. Based on the converted section characteristic method, the deformation increment control differential equation of composite shear wall was established. the calculation formula of deformation increment under different loads was given, and the influence of load, slip stiffness and temperature on deformation increment was calculated and analyzed. The results show that the parabolic loading form has the greatest effect on the deformation. As the slip stiffness was increased by 6 times, the deformation increment was reduced by about 98%. When the temperature increased from 20°C to 40°C, the deformation increment showed an ascending parabola, but the total deformation increment remained relatively unchanged
