［摘要］武漢中建·光谷之星屬于體型復(fù)雜的混合結(jié)構(gòu)，結(jié)構(gòu)平面及豎向布置均不規(guī)則，屬特別不規(guī)則類型結(jié)構(gòu)。工程集混凝土、鋼結(jié)構(gòu)、型鋼混凝土等多種材料構(gòu)件為一體，在建筑屋面層通過最大跨度76.5m的連體桁架將G，H，I三個(gè)地塊塔樓連接為一個(gè)整體。介紹了這一項(xiàng)目的結(jié)構(gòu)特點(diǎn)，分析了結(jié)構(gòu)在地震下的響應(yīng)。結(jié)果表明，本工程采用的結(jié)構(gòu)形式安全可靠，本項(xiàng)目通過將橋梁工程中使用的摩擦擺支座用做連體桁架支座，有效地釋放了超長連體結(jié)構(gòu)的溫度應(yīng)力。

Abstract:The Optics Valley Star of CCTEB in Wuhan is a complex mixed structure with irregular arrangements in horizontal plane and vertical plane. It is a particularly irregular type structure. Various materials and members are adopted in this project such as concrete, steel and steel-reinforced concrete. On the top floor of the building, the towers of the three plots G, H and I are connected as a whole by connecting steel truss with a span of about 70m. The structural characteristics of this project were introduced, and the response of the structure to earthquakes was analyzed. The results show that the structural form adopted by this project is safe and reliable. In this project, the friction pendulum bearing used in the bridge project is used as a connected truss bearing, which effectively releases the temperature stress of the super-long connected structure.
Keywords:Optics Valley Star of CCTEB in Wuhan; complex mixed structure; friction pendulum bearing; connecting truss
