Seismic Responses and Design of Steel Plate Shear Wall

Abstract

This paper presents the experimental and analytical results of four large scale steel panel shear wall(SPSW) frames tested in NCREE.Three of the SPSW frames are constructed with restrainers,and the fourth one is without any out-of-plane buckling restrainer.Test confirmed that the proposed restrainers can effectively reduce the magnitude of the buckling sound and the out-of-plane buckling of a SPSW subjected to large inter-story drifts.It also enhances the energy dissipation capacity of the SPSW frame.This paper introduces the design procedures of these SPSWs and the restrainers.In addition,two analytical models: namely strip model and equivalent braced(EB) model,are described and applied on the test specimens.The computation of the material yield strength of the EB is described.Analytical results suggest that both the EB model and the tension-only strip model can satisfactorily predict the inelastic response of the SPSWs.
