Tower and podium are combined together with multi layers space truss. Structure system is complexand many indexes exceed the limit so it belongs to super high-rise building. The structure system and design contents of each part were introduced. Dynamic elastic-plastic time history analysis was done by PERFORM-3D in order to analyze the performance of the structure under rare earthquake. Based on the resultsspecial treatments were taken to the vertical componentsvertical curtain type atrium and large-span space truss. At the same timein order to accurately calculate the effective length of bottom three layer columnsthe whole buckling stability analysis was done. Keywords structure system super high rise structure performance-based design large-span space truss buckling stability analysis 1 CAMEO 凯 模 CAE 库 案 例 35 m 2 1 47 1 ~ 9 6m 4. 2m 214. 8m 196. 8m 7 42m 3 10 m 2 2 1 2 400mm 900 ~ 500mm 2. 1 80 ~ 35mm + 7 H 1 000 ~ 500mm 9 3 Q345B MIStructE CEng Email zhangjin@ sipdri. com
