Abstract

Abstract

The knee bracing steel frame(KBF) is a new kind of energy dissipating frame,which combines excellent ductility and lateral stiffness.As the structural fuse of the frame,the knee element will yield firstly under major earthquake so that no damage occurs to the major structural members and the rehabilitation will then be easy.To help fully understand the relations between the seismic performance and the structural parameters,systematic elastoplastic analysis of the KBF structure was conducted using the finite element method(FEM).Finally,general design recommendations were made according to the results of the FEM analysis.
