［摘要］南京南站G84-E地塊E2#樓是一大跨度高位轉(zhuǎn)換復(fù)雜高層建筑，該項目具有轉(zhuǎn)換跨度大、結(jié)構(gòu)荷載重、兩翼剛度小及平面不規(guī)則等特點(diǎn)，給結(jié)構(gòu)設(shè)計帶來了眾多亟待解決的重難點(diǎn)問題。根據(jù)結(jié)構(gòu)體系特點(diǎn)，分別從結(jié)構(gòu)抗震性能指標(biāo)、建筑功能、施工難度和經(jīng)濟(jì)合理性等方面，重點(diǎn)分析了轉(zhuǎn)換構(gòu)件方案和抗側(cè)力體系選型，并結(jié)合大震彈塑性分析結(jié)果，提出采用屈曲約束支撐解決部分柱達(dá)到屈服狀態(tài)的問題。最后,對此類大跨度高位轉(zhuǎn)換復(fù)雜結(jié)構(gòu)體系在選型中應(yīng)注意的問題和解決方案進(jìn)行了總結(jié)。

Abstract:The E2# building of G84-E plot of Nanjing South Railway Station is a large-span complex high-rise building with high-position transfer. The project has the characteristics of large-span transfer, heavy structural load, small stiffness of two wings and plane irregularity, which brings many important and difficult problems to the structural design. According to the characteristics of the structural system, the transfer component scheme selection and the selection of the lateral force resistant system were analyzed emphatically from the aspects of the structural seismic performance index, building function, construction difficulty and economic rationality. Combined with the elastic-plastic analysis results under the rare earthquake, the buckling-restrained brace was proposed to solve the problem that some columns reached the yield state. Finally, the problems and solutions that should be paid attention to in the selection of this kind of large-span complex structural system with high-position transfer were summarized.
Keywords:large span; high-position transfer; complex structure; buckling-restrained brace(BRB)
