Abstract:Shenyang Wealth Center adopts frame-corewall structural system with the main structural height of 179.9m. The structural layout, main characteristics, out-of-code situation and performance-based seismic fortification objectives of the structure were briefly introduced. Two programs, PKPM and ETABS, were used to perform elastic analysis of the structure under frequent earthquakes, fortification earthquakes, and wind loads, and the bearing capacity analysis of components was conducted. LS-DYNA program was used to conduct the elastic-plastic dynamic time-history analysis under rare earthquakes, and the overall control index of the structure and the plastic development of key components were studied. The FLUENT program was used to carry out wind tunnel simulations of the single building with and without considering the interference effect of podium respectively, and the shape coefficient of the structure was obtained. The analysis results show that the design indexes of the structure meet the requirements of the code, the key components meet the set seismic performance objectives, and the structure has good seismic performance; the podium building has obvious interference to the tower, and the shape coefficient selected in the design can meet the wind tunnel numerical simulation results and codes requirements.
