Abstract:Office building a in district a of Taiyuan Yuanda Shopping Mall Center has height of 143-20m, and its main structure adopts reinforced concrete frame-corewall structural system. The characteristics of the engineering structure and the out-of-code situation were mainly introduced, and corresponding strengthening measures in view of the out-of-code situation were put forward, so as to ensure the safety, reliability and economic rationality of the overall structure. Several kinds of software such as YJK, PMSAP and SAUSAGE were used to calculate and analyze the structural performance under frequent earthquake, fortification earthquake and rare earthquake. The tensile stress of corewall shear wall under fortification earthquakes was supplemented and the buckling analysis of local cross-layer columns was carried out. The results show that the strengthening measures proposed in the structural design are safe and effective, and can achieve the performance-based seismic design goals of "three-level".

Keywords:Taiyuan Yuanda Shopping Mall Center； super high-rise building; performance-based seismic design; elastoplastic time-history analysis; tensile stress of wall; buckling analysis
