［摘要］珠海橫琴鐵建廣場項目屬于四塔高位連體超高層，結(jié)構(gòu)存在較多不規(guī)則類型。高度和動力特性相差較大的四棟塔樓之間連接形式的選擇以及鋼結(jié)構(gòu)連橋結(jié)構(gòu)設(shè)計是本項目要解決的重要設(shè)計問題。經(jīng)過方案比選，對選定的連橋連接形式和滑動支座、阻尼器的設(shè)計原則進(jìn)行了分析和計算驗證，最終設(shè)計基本做到了結(jié)構(gòu)體系安全、合理、經(jīng)濟(jì)。減隔震技術(shù)的使用，有效地減小了小震和風(fēng)荷載作用下連橋支座位移，使得連橋在大震下受力更加均勻，減小了連橋與塔樓之間的相互作用，取得了良好的經(jīng)濟(jì)效益。

Abstract:Hengqin Tiejian Plaza Project in Zhuhai belongs to the high-elevation connected four-tower super tall structure with many irregular patterns in the structure. Important design problems to be solved in this project include the selection of connection form between four towers with large difference in height and dynamic characteristics as well as the structural design of steel structure bridge. After the scheme comparison and selection, the selected connection form of the bridge, the design principle of sliding bearing and damper were analyzed and verified by calculation. The final design basically achieved the safety, rationality and economy of the structural system. The application of the technology of vibration reduction and isolation design effectively reduces the displacement of the bearing of the bridge under the action of frequent earthquake and wind load, to make the bridge bear more uniform forces under the action of rare earthquake and reduce the interaction between the bridge and the tower, and obtain good economic benefits.
Keywords:Hengqin Tiejian Plaza Project in Zhuhai; high-elevation connected four-tower building; wind vibration comfort; vibration reduction and isolation design; wind resistance design
