Abstract:“Xing Chuang City”shopping mall in Hangzhou has a building height of 30. 8m and a length of 300m. It is a largecomplex high-rise reinforced concrete frame structure. In order to achieve the predetermined design performance goal of thestructure, firstly,the problem of the regularity of the plane elevation was solved conceptually by joint setting. Then, by usingYJK and MIDAS Gen, the elastic calculation and time-history analysis of the main structure under frequent earthquake,seismic performance design of fortification intensity and elastic-plastic time-history analysis under rare earthquake werecarried out. In addition, the mid-earthquake calculation was carried out for the large opening slab, and the supplementarycalculation was made for the temperature stress of the super-long slab. And finally, the problems of anti-pressure,anti-floating of the basement under the subway line and the problem that the pile foundation and natural foundation worktogether to reduce the deformation difference was analyzed. Through the calculation and analysis of the above-mentionedsteps and taking targeted strengthening measures for the key components and important parts, such as increasing thestiffness of the outer ring structure, using structural steel at the root of large cantilever beams, strengthening stressconcentration points on the floor slabs, and providing grouting holes in the bottom plate,the structure has achieved thepredetermined design performance goal.
Keywords: high-rise structure; performance-based seismic; transfinite judgment; floor opening; elastic time historyanalysis; temperature stress; subway roof
