［摘要］大連世界金融中心為雙塔超限超高層建筑，核心筒尺寸偏小，核心筒高寬比達(dá)到19-7，抵御水平荷載作用的能力偏弱。結(jié)構(gòu)設(shè)計(jì)采用不落地鋼框架支撐+混凝土核心筒雙重抗側(cè)體系，以彌補(bǔ)抗側(cè)剛度的不足。主要介紹該項(xiàng)目設(shè)計(jì)過(guò)程中的幾個(gè)難點(diǎn)，包括結(jié)構(gòu)方案比選過(guò)程，抗震性能化設(shè)計(jì)及相關(guān)的計(jì)算分析等；總結(jié)了與不落地鋼支撐系統(tǒng)相關(guān)的幾個(gè)復(fù)雜問(wèn)題。結(jié)果表明，該體系滿足結(jié)構(gòu)承載力與抗震性能化要求。

Abstract:Dalian World Financial Center is a double-tower super high-rise building with small size of corewall which height-width ratio of 19-7, which is weak in resisting horizontal load. The structural design adopted the double anti-lateral system of non-landing steel frame support+concrete corewall to make up for the lack of anti-lateral stiffness. Several difficulties in the design process of the project were mainly introduced, including the process of structural scheme comparison and selection, seismic performance-based design and relevant calculation and analysis. Several complex problems related to non-landing steel support system were summarized. The results show that the system meets the requirements of bearing capacity and seismic performance.

Keywords:non-landing steel support; composite structure; corewall depth-width ratio
