Abstract

Abstract

To improve seismic performances of cold-formed steel framed shear walls, a self-centering energy-dissipation brace was proposed, and its configuration and working principle were presented. A finite element analysis model was constructed to study the mechanical properties,a simplified simulation method of self-centering energy-dissipation braces was proposed. The hysteresis curves of cold-formed steel shear walls with or without braces were compared,the variable parameter analysis of self-centering energy dissipation braces was conducted to analyze the effects of preloading, disc spring stiffness and friction on the seismic performance of the wall. The research results showed that adding self-centering energy-dissipation braces could improve the bearing capacity of the wall, enhance the energy dissipation capacity and ductility of the wall, reduce the residual deformation of the structure and improve the seismic performances of the wall;the residual deformation of the wall decreased with increasing disc spring stiffness, and preloading and increased with increasing friction.
