The building height of the five-star hotel in Suzhou is 79.050m,and the structural form is frame-shear wall structure.There are no seismic joints between the main tower and the podium.There are four irregular items in the structure,such as torsional irregularity,floor discontinuity,stiffness mutation and local layer through column and V-shaped inclined column.The structural scheme,performance target and overall calculation results were introduced.In view of the small height of the hotel equipment conversion layer,the solutions and the mechanical properties of the layer through column were put forward and V-shaped inclined column were analyzed in detail,the floor at the top of the V-shaped inclined column was analyzed by finite element method.Two kinds of finite element software YJK and PMSAP were used to analyze the the structure under frequent earthquake,and the supplementary calculation of elastic time history was carried out.The elastoplastic dynamic time history analysis of structure under rare earthquake was carried out by using the software of SAUSAGE.The performance level of the structure under the rare earthquake was evaluated,and the strengthening measures of structure were put forward.The structure can reach the predetermined seismic performance index and the seismic performance is good.
