To be a new type of building component, composite shear wall with steel tubes bundle has been widely used in the steel structure housing system as the development of prefabricated construction. In this paper, ABAQUS has been used to analyze mechanical performance of composite shear wall under low cycle reciprocating loading conditions. 6 group simulations with different axial compression ratio have been carried out, and both hysteretic curve and skeleton curve have been drawn. The simulation results showed that hysteretic curves become full before composite shear wall damage, and seismic performance is good. When the axial pressure ratio is 0.2, the bearing capacity of composite shear wall with steel tubes bundle achieves its maximum value. The bearing capacity of composite shear wall with steel tubes bundle also was calculated using classical shear wall formulation, the results are consisting with finite element simulation.
