摘　　要：云南省某医院住院楼采用钢支撑(BRB)-钢筋混凝土框架结构体系,采用YJK、SAP2000两种软件对结构进行多遇地震下的反应谱及弹性时程分析、罕遇地震下的动力弹塑性分析。分析结果显示罕遇地震作用下减震结构与非减震结构的水平位移比小于0.75,绝大多数屈曲约束支撑(BRB)进入塑性阶段,框架梁出现大量塑性铰而无柱铰出现;表明该结构体系选取、结构布置合理,结构在设置了屈曲约束支撑(BRB)后,具有了良好的抗震耗能机制,有效提高了结构主体的安全性。In a hospital inpatient building in Yunnan Province,steel brace(BRB)-concrete frame structure system is adopted.YJK and SAP2000 software are used to analyze the response spectrum and elastic time history of the structure under frequent earthquakes as well as the dynamic elastic-plastic analysis under rare earth-quakes.The analysis results show that the horizontal displacement ratio of the shock-absorbing structure and the non-shock-absorbing structure is less than 0.75 under rare earthquakes.Most of the buckling restrained braces(BRB)enter the plastic stage,and a large number of plastic hinges appear in the frame beams without column hinges.It shows that the selection of the structure system and the layout of the structure are reasonable,and the structure has a good seismic energy dissipation mechanism after the installation of the buckling restrained braces(BRB).It effectively improves the safety of the main body of the structure.
