Abstract

This study explores the seismic benefits of a steel structure with Horizontal Self-Centering Structural System (H-SCSS) between Vertical Lateral Force Resisting Systems (VLFRS) and the floor diaphragm. The H-SCSS enables decoupling, facilitating relative displacement and energy dissipation. Comparing nonlinear cyclic quasi-static, and time history analyses on a Special Concentrically Braced Steel Frame (SCBF-X, ASCE 7), with and without H-SCSS, reveals reduced residual drift, energy dissipation concentrated in fuses, significantly lower energy demand for VLFRS, increased ductility, and decreased stresses and inelastic deformations in vertical lateral resistance systems when using H-SCSS.
