Cyclic behavior and performance of a coupled-steel plate shear wall with fuse pin
Mahdi Usefvand, Ahmad Maleki and Babak Alinejad

    Coupled steel plate shear wall (C-SPSW) is one of the resisting systems with high ductility and energy absorption. Energy dissipation in the C-SPSW system is accomplished by the bending and shear behavior of the link beams and SPSW. Energy dissipation and floor displacement control occur through link beams at low seismic levels, easily replaced after an earthquake. In this study, a coupled steel plate shear wall with a yielding fuse is presented. The system uses a high-ductility fuse pin element instead of a link beam, which has good replaceability after the earthquake. In this study, four models of coupled steel plate shear walls were investigated with I-shaped link beam, Ishaped link beam with reduced beam section (RBS), box-link beam with RBS, and fuse pin element under cyclic loading. The finite element method was used through ABAQUS software to develop the C-SPSW models. To verify the finite element model results, two test specimens of coupled steel plate shear walls were validated. Comparative results of the hysteresis curves obtained from the finite element analysis with the experimental curves indicated that the finite element model offered a good prediction of the hysteresis behavior of C-SPSW. The results of the C-SPSW models revealed that the fuse pin caused an increase in the ultimate capacity by approximately 19% and the energy dissipation by 20% compared to the other C-SPSW.
