Abstract:Rizhao China Resources Center Commercial Phase II, with a total construction area of about 150 000 square meters, has 3 floors underground and 50 floors above ground. The height is 182-6m above the embedded layer. The structure belongs to the building with the height exceeding level-B height. The tower adopts the frame-corewall structural system, and the attached commercial podiums adopt frame-shear wall structural system. The 1~9 floor of the project is a hotel, which has high requirement for the cross-section of the frame columns. The concrete-filled steel tube(CFST) superimposed columns were used to meet the requirements of the building. There are some out-of-code items in the project, such as torsion irregularity, large-span transformation of podiums and banquet hall, and partial discontinuity of floor slabs. In the design process, the overall seismic performance of the structure was analyzed, including elastic calculation under frequent earthquake, elastic time-history analysis under frequent earthquake，elastic and unyielding calculation under fortification earthquake, unyielding calculation and dynamic elastic-plastic analysis under rare earthquake, etc. The  stress analysis was carried out for the  corewall coupling beams supporting the large-span secondary beams and the notched  beams around the corewall. Results show that the structural integral analysis and component calculation analysis meet the requirements of the code, and the structure is safe and reliable.

Keywords:out-of-code high-rise structural design; CFST superimposed column; secondary structure for apartment loft; stress analysis of coupling beam; stress analysis of notched beam
