Abstract:The steel trusses can be used to replace the normal reinforcement to form the precast steel truss-concrete composite shear wall, which is conveniently prefabricated and installed and very suitable for prefabricated constructions.Seismic analysis model of steel-concrete shear wall was established by ABAQUS and validated by test data.Thus, the seismic performance of precast steel truss-concrete composite shear wall was studied by the model, and the cyclic loading simulation on five steel truss-concrete shear walls with different design parameters was carried out to investigate the influence of axial compression ratio and steel content on its hysteretic performance, deformation capacity, stiffness degradation and energy dissipation capacity. The results show that the increase of axial compression ratio is disadvantageous to the deformation capacity and energy dissipation capacity of the shear wall. Increasing the steel ratio of the truss chord can effectively improve the shear bearing capacity of the shear wall, and increasing the steel ratio of the truss web has significant effects on improving the energy dissipation capacity of the shear wall, but has little effect on the load bearing capacity.
