摘　　要：杭州某连体高层创伤中心结构高度为863m,由两座塔楼和裙房组成。该建筑主体结构采用钢筋混凝土框架-剪力墙结构体系,双塔在16-18层通过钢结构连廊连接为一体,其跨度为33m,宽度为16m。为了减小连接体构件内力,减小构件截面尺寸,减小施工难度并减少对建筑方案的影响,钢结构连廊与主体结构的连接采用弱连接形式。在设计阶段,对该超限高层建筑结构的关键部位和关键构件进行了精细分析,并进行了弹性和动力弹塑性时程分析,以确保结构和各类构件的抗震性能可以达到预定的目标。计算结果表明,该连体结构体系可以满足承载力、抗侧力、变形和舒适度的要求。The Hangzhou trauma center is a conjoined high-rise building with a structural height of 863 meters,consisting of two towers and a podium.The main structure of the building adopts a reinforced concrete frame-shear wall system.The two towers are connected by a steel structure corridor on the 16th to 18th floors,with a span of 33 meters and a width of 16 meters.To reduce the internal force of the connecting components,decrease the size of the section,and reduce the difficulty of construction and the impact on the building scheme,the connection between the steel structure corridor and the main structure adopts a weak connection.In the design phase,the critical parts and components of the structure of this super high-rise building were analyzed in detail,and elastic and dynamic elasto-plastic time history analysis were conducted to ensure that the seismic performance of the structure and various components can meet the predetermined targets.The calculation results show that the connected structural system can meet the requirements of bearing capacity,lateral resistance,deformation and comfort.
