摘要: 蘇州國際會議酒店主樓為連體結(jié)構(gòu),結(jié)構(gòu)高度為 91.4m,由兩棟基本對稱的塔樓通過跨度為 81m 的鋼連廊連成一個整體. 其中塔樓采用框架-剪力墻結(jié)構(gòu)體系,鋼連廊采用桁架結(jié)構(gòu)體系. 針對結(jié)構(gòu)特點,對塔樓及連接體進行多遇地震、設(shè)防地震和罕遇地震下的分析,對比了結(jié)構(gòu)單塔及整體結(jié)構(gòu)的動力特性及受力性能,探討了連接體對整體結(jié)構(gòu)受力性能的影響. 結(jié)合超限情況,對結(jié)構(gòu)進行了性能化設(shè)計,并采取了相應(yīng)的抗震措施對關(guān)鍵性構(gòu)件進行加強. 分析結(jié)果表明,結(jié)構(gòu)能夠達到既定的性能目標,結(jié)構(gòu)體系合理可靠. 針對連廊在施工和使用階段存在的不利因素,提出了連廊整體提升、支座調(diào)平、防墜落等施工措施.

Abstract: The main building of Suzhou International Conference Hotel is a connected structure with a structural height of91.4m. It consists of two symmetrical towers connected by a steel corridor with a span of 81m. The tower is a frame-shearwall structure and the steel corridor is a truss structure. According to the structural characteristics, the tower and connectorwere analyzed under frequent earthquake, fortification earthquake and rare earthquake. The dynamic characteristics andmechanical performance of single tower and overall structure were compared, and the influence of the connector on themechanical performance of overall structure was discussed. Combined with the over-limit situation, the performance-baseddesign of the structure was carried out, and the corresponding seismic measures were taken to strengthen the keycomponents. The analysis results show that the structure can achieve the established performance goal, indicating that thestructural system is reasonable and reliable. The construction measures of overall lifting of the corridor, leveling of thebearings and drop prevention were implemented to prevent disadvantages in the construction and use stage of the corridor.
