摘要
昆明地铁线网控制中心工程塔楼为超高层全钢结构,结构总高度150 m,采用钢框架中心支撑结构体系,外部采用跃层钢支撑,内部采用防屈曲约束支撑(BRB)。对地铁线网控制中心设计使用年限及地震作用取值进行探讨;论述超高层钢结构结构选型及结构布置思路;对高烈度地区抗震设计相关的弹性时程及弹塑性时程进行分析,探讨屈曲约束支撑减震技术应用。
The tower of Kunming Metro Line Control Center project is a super high-rise and all steel structure.The total height of the structure is 150m.The central support structure system of steel frame is adopted, the outer layer steel support is used, and the buckling restrained braces （BRB） are used inside.The discussion on the subway network control center design life and earthquake action ; discusses the high-rise steel structure selection and structural arrangement of ideas ; the elastic seismic design in high intensity area and time history analysis ; elastoplastic analysis ; buckling restrained brace application of shock absorption technology.
