［摘要］華強(qiáng)金廊城市廣場（一期）3#樓為框架-雙核心筒結(jié)構(gòu)體系，框支柱采用型鋼混凝土柱，6層為轉(zhuǎn)換層。采用PERFORM-3D軟件對華強(qiáng)金廊城市廣場（一期）3#樓超高層結(jié)構(gòu)進(jìn)行彈塑性時(shí)程分析，并對轉(zhuǎn)換梁方案和轉(zhuǎn)換斜墻方案進(jìn)行分析對比，通過層間位移角、樓層剪力、構(gòu)件耗能和構(gòu)件損傷等計(jì)算結(jié)果得出，轉(zhuǎn)換梁方案的框支剪力墻在大震作用下出現(xiàn)剪切破壞，轉(zhuǎn)換框架的屈服程度和范圍較大；轉(zhuǎn)換斜墻方案的斜墻在大震作用下未出現(xiàn)剪切破壞，避免了由于剛度突變使斜墻過早出現(xiàn)破壞，轉(zhuǎn)換框架的屈服程度和范圍較小，滿足抗震性能要求。

Abstract:Huaqiang Gold Corridor City Square (Phase 1) 3# building adopts frame-double corewall structural system. Steel-reinforced concrete column is applied for the frame-supporting column, and the sixth layer is the transfer layer. PERFORM-3D software was applied to carry out elasto-plastic time-history analysis on the super high-rise structure of Huaqiang Gold Corridor City Square (Phase 1) 3# building. And two schemes of transfer beam and transfer inclined wall were compared. The story drift ratio, story shear, component energy dissipation and component damage in the two schemes were analyzed. The results indicate that in transfer beam scheme, shear failure occurs in frame-supporting shear wall and transfer frame has a wide degree and range of yield. Shear failure is not observed in the transfer inclined wall scheme under the rare earthquake, which avoids early failure of inclined wall due to the stiffness mutation. And transfer frame has a little degree and range of yield which can satisfy the seismic performance requirements.
Keywords:transfer inclined wall; transfer beam; super high-rise building; stiffness mutation; elasto-plastic time-history analysis; shear failure
