［摘要］青岛华润大厦项目地下4层，地上56层，结构高度237-30m，塔冠高度260-00m，属于超B级高度建筑，采用框架-核心筒结构体系。核心筒相对于塔楼偏置，塔楼相对于大底盘裙房偏置，且裙房在3～5层通过40m跨的钢连桥与已建成的青岛华润万象城相连。结构抗震设计采用规范性能化设计方法，采取SATWE，MIDAS Building，PKPM-SAUSAGE等软件进行了弹性计算、弹性时程分析以及弹塑性时程分析，保证结构在多遇地震作用下完全处于弹性，关键构件及部分主要构件能够实现设防地震、罕遇地震作用下的性能目标。通过合理的结构布置和相应构造、加强措施使项目的不规则程度得到了有效控制。

Abstract:The Qingdao China Resources Building project has 4 floors underground and  56 floors above ground, with  structural height of 237-30m and  tower crown height of 260-00m. It belongs to a super-B height building and adopts frame-core tube structure system. The core tube is biased relative to the tower, and the tower is biased relative to the large chassis podium. The podium is connected to the completed Qingdao MIXC through a 40m-span steel bridge at 3～5 stories. The seismic design of the structure adopts the performance-based design method specified in the codes. The elastic calculation, elastic time history analysis and elasto-plastic time history analysis were carried out by using SATWE, MIDAS Building, PKPM-SAUSAGE softwares, which can ensure that the structure is completely elastic under frequent earthquakes, and the key components and some main components achieve the performance targets under medium earthquakes and rare earthquakes. Through reasonable structural arrangement and corresponding construction and strengthening measures, the degree of irregularity of the project has been effectively controlled.

Keywords:super-B height building; core tube bias; core tube backsetting; tower bias; performance-based design
