Modeling and Analysis of Composite Steel Plate Shear Wall with Assembled Multi-concrete Slab

This paper presents numerical investigation of composite steel plate shear wall with vertical assembling mode (V-CSPSW) affecting cyclic loading. Three-dimensional finite element models are developed using ABAQUS emphasizing constitutive material modeling and element type to represent the real behavior of V-CSPSW. Validation of the FE model against the experimental results has shown a good agreement. The numerical studies were focused on the effects of gap width, bolt spacing-to-steel thickness ratio and concrete slab thickness on the V-CSPSW's behavior. Results indicate that the gap width should less than 48mm and 72mm if the bolt spacing-to-steel thickness ratio is 100 and 125, respectively; meanwhile, the bolt spacing-to-steel thickness ratio of the V-CSPSW should less than 125 if the concrete slab possesses enough restraint stiffness.
