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
