摘要

摘要: 斜隅支撑框架体系(KBF)是一种新型耗能支撑框架钢结构体系，它具有延性好、抗侧移刚度大、震后容易修复的特点。结构主要构件在隅撑的保护下即使受到罕遇地震荷载作用也不易受到损伤。为此采用有限元方法(FEM)对此类结构进行了系统的弹塑性受力分析，全面总结了其抗侧移受力性能与各结构参数间的关系，并总结得出适合设计实用的一般规律。

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.
