Abstract:
The mechanics law for boundary elements of buckling restrained steel plate shear wall (BRSPSW) with two-side connections was studied using theoretical analysis and finite element method. The force transferring model and internal force calculation method for boundary elements were presented. Structural analysis of frame-BRSPSW could be conducted using proposed equivalent brace model to replace BRSPSW. In order to validate the presented method, frame-BRSPSW and frame-equivalent brace structures with different stories and different spans were analyzed. Furthermore, the comparison of internal force for beam and column was carried out, and the effects for steel plate shear wall arrangement on the internal force, deformation of boundary elements were analyzed. The results show that the equivalent brace model can accurately simulate the effect of BRSPSW to the boundary elements. The width of steel plate shear wall is recommended to be more than 1/3 of the span, and the steel plate shear wall is arranged in the middle of the span. If the width of the steel plate shear wall is less than 1/3 of the span, it should be well to be placed near the end of the beam.
