(1 College of Civil Engineering, Chongqing University, Chongqing 400045, China; 2 Hong Kong Hua Yi Design Consultants(S.Z.)Ltd., Shenzhen 518031, China)Abstract: The advantages of two kinds of materials, concrete and steel, can be fully played in steel plate concrete composite shear wall, and the shear bearing capacity of shear wall can be substantially increased in addition to good ductility, therefore steel plate-concrete composite shear walls are widely used in super high buildings. Based on the existing test research results and concrete mechanics theory, the method to detemune the constitutive relationship of shear material used for modeling steel plate concrete composite shear wall in PERFORM-3D is proposed. The rationality of the proposed modeling method is verified by the comparison with the finite element analysis results of ABAQUS. The global structural ealsto-plastic analysis for steel plate-concrete composite shear wall structures can be carried out in PERFORM-3D by use of the proposed analysis model in tlus paper.
Keywords: steel plate-concrete composite walls; finite element analysis; ABAQUS; PERFORM-3D
