［摘要］九方城市廣場(chǎng)位于天津?yàn)I海新區(qū)，為大底盤(pán)多塔結(jié)構(gòu)。三棟塔樓中，一棟高212.4m的超高層辦公樓為鋼筋混凝土框架-核心筒結(jié)構(gòu)，另外兩棟高度分別為99.35，92.25m的公寓，為高位轉(zhuǎn)換的部分框支抗震墻結(jié)構(gòu)。介紹了超高層及高位轉(zhuǎn)換結(jié)構(gòu)的抗震性能目標(biāo)設(shè)置、薄弱層樓板的分析方法等問(wèn)題，著重討論了加強(qiáng)層設(shè)置對(duì)超高層結(jié)構(gòu)剛度的影響及高位轉(zhuǎn)換情況下轉(zhuǎn)換層的加強(qiáng)措施。通過(guò)彈塑性分析研究了開(kāi)洞框支梁在罕遇地震下的受力特點(diǎn)和抗震性能。

Abstract: The Jiufang Town Plaza is located in the Tianjin New Coastal Area, which is a 3-tower structure with an enlarged base. One of the towers is a super high-rise office building with 212.4 meters high, which is a reinforced concrete frame-core wall structure. The other two towers are apartment buildings with 99.35meters and 92.25 meters high respectively, which are partly frame supported shear wall structures with a high level transfer story. The determinations on seismic performance objects are discussed for a super high-rise building and a high level transfer story building, and analysis methods on slabs with weak situations. It emphasizes on impacts of story with outriggers to the structural stiffness, the enhancement measures on outriggers of a high level transfer story, and studies the seismic performance of the structure with hole under rare earthquake by elasto-plastic analysis.

Keywords: super high-rise building; multi-tower structure; enlarged base; story with outriggers; high level transfer story
