摘　　要：厦门裕景中心项目主体为框架—剪力墙结构,平面呈S形,上部结构的5~7层中间部分设置转换桁架用于支撑上方11层钢结构,存在细腰、扭转不规则、偏心布置、托柱转换、底盘高度超限等多项不规则情况。该项目为续建工程,上部荷载较原来有所增加,需重新复核基础承载力,并基于抗震性能设计,设置合理的抗震性能目标,通过罕遇地震下的动力弹塑性时程分析,找出薄弱部位,从而提出可行加强措施。最后,分析交叉桁架节点应力及小震中震下转换桁架的传力途径,确保达到中震性能目标。The main body of the project is a frame-shear wall structure with an S-shaped plane.The middle part of the 5 to 7 layers of the superstructure is equipped with transfer trusses to support the upper 11 layers of steel structure.There are many irregularities such as thin waist,irregular torsion,eccentric arrangement,column conversion,and excessive chassis height.The upper load of the project is increased from the original,so it is necessary to re-examine the bearing capacity of the foundation,and set reasonable seismic performance targets based on the seismic performance design.Through the dynamic elastic-plastic time-history analysis under rare earthquakes,the weak parts are identified and feasible strengthening measures are proposed.Finally,the joint stress of the cross truss and the force transfer path of the transfer truss under small epicenter are analyzed to ensure that the performance target of medium earthquake is achieved.
