摘　　要：在某培训中心钢结构工程中,采用消能支撑有效解决了设计过程中出现的层间侧移延性比不满足要求的问题。通过在梁与支撑节点设置金属屈服阻尼器,将普通钢支撑改造成消能支撑,并给出了阻尼器安装位置的节点示意图。计算分析结果表明,消能支撑与普通钢支撑相比,可以有效减小结构在地震作用下的位移反应,提高结构的安全储备,具有良好的经济效益。In the actual project of a steel structure,the energy dissipation braces were used to solve the problem that the ductility ratio of inter-story displacement cannot satisfy the demand.Ordinary steel braces were reformed to energy dissipation braces through installing the energy dissipation devices on the joint of brace and beam,and the joint diagram was given.The calculating results show that energy dissipation braces can reduce the displacement response of building under earthquake effectively,ensure the structure safety and save the engineering cost.
