Abstract: The structural design of Citic Pacific super high?rise office in Suzhou was introduced. Through theperformance?based seismic design, the structure can meet the requirements of the code. The tensile stress of the wall limbwas checked under the action of moderate earthquake, and the tensile force of the wall limb was shared by setting sectionsteel at the four corners of the core tube. The dynamic elastic?plastic time?history analysis of the structure under largeearthquake was carried out by using SAUSAG software. The influence of the unclosed outer frame beam on the seismicperformance of the structure was analyzed. The analysis show that the yield sequence of the components meets theconceptual design requirements of the structural seismic engineering, and the structure has good deformation capacity andcan achieve the expected seismic performance target. The unclosed corner of the outer frame beam has little effect on theoverall seismic performance of the structure, and the frame part can still play the second line role of the defense.

Keywords:frame?core tube structure; super high?rise structure;performance?based seismic design; unclosed outer frame beam
