［摘要］重慶江北嘴金融城2號(hào)項(xiàng)目結(jié)構(gòu)體系較復(fù)雜，設(shè)計(jì)難點(diǎn)較多。對(duì)該項(xiàng)目結(jié)構(gòu)設(shè)計(jì)過(guò)程中的若干問(wèn)題進(jìn)行了總結(jié)和闡述，比如超長(zhǎng)地下室的樓板溫度應(yīng)力分析及針對(duì)性設(shè)計(jì)措施；抗震性能分析與設(shè)計(jì)；大跨度鋼結(jié)構(gòu)連廊的結(jié)構(gòu)設(shè)計(jì)；大跨度鋼結(jié)構(gòu)連廊的舒適度分析和TMD減振設(shè)計(jì)；支撐連廊的鋼骨混凝土大懸挑結(jié)構(gòu)的分析與設(shè)計(jì)。設(shè)計(jì)中，針對(duì)以上難點(diǎn)采取了相應(yīng)的措施，既滿足了結(jié)構(gòu)安全，也達(dá)到了建筑效果要求。

Abstract: The structural system of Chongqing Financial Center No.2 is complex, so the design is difficult. A number of issues during the process of structural design for this project were summarized and expatiated, as follows: the stress analysis of floor temperature for the super-long basement and related design measures, the analysis and design of seismic performance, the structural design of large-span steel corridor, the analysis of comfort level and the TMD damping design about the largespan steel corridor, the analysis and design of the big cantilever structure which was steel reinforced concrete and used to support the corridor. The measures for above mentioned difficulties were carried out during the design, and the results showed that the structure system not only met the requirements of the structural safety, but also reached the performance requirements of the building.

Keywords: super-long basement; performance-based design; reinforced concrete; comfort level; TMD
