［提要］介绍钢结构铰接框架支撑体系中支撑和节点板的震害、实验室的抗震性能研究、有关规范的规定和具有延性性能的支撑和节点板的设计概念及方法。由于我国现行建筑抗震规范中尚不包括钢结构铰接框架支撑体系，故文中提出的抗震设计原则、规范规定和计算公式，可供从事钢结构设计和研究的技术人员参考。

［关键词］钢结构建筑；支撑；节点板；抗震设计；延性

Seismic Design of Braces and Gusset Plates with Ductile Behavior/Sun Yusong (Northeast Electric Power Design Institute of China Power Engineering Consulting Group，Changchun 130021，China)Abstract:It is presented concisely the aftermath of earthquakes, seismic behavior in laboratories and relevant code provisions of bracings and gusset plates in the braced frame system, and conception and method for seismic design of gusset plates for ductile performance. Due to steel braced frame system is not covered in current Code for seismic design of buildings of China, principles, code provisions and formulas for seismic design can be referred for engineers in design and research.

Keywords:structural steel building; bracing; gusset plate; seismic design; ductile
