摘要: 東西匯連體雙塔的塔樓高度分別為 119、167.3m,高位連接體跨度約 70m,塔樓與塔樓之間及塔樓與連接體之間的主抗側力角度均有夾角,為高位大跨度斜交連體超限結構.主體雙塔分別采用框架-剪力墻結構體系、框架-核心筒結構體系,連接體為鋼桁架體系.根據(jù)結構的超限情況合理選取抗震性能化設計目標,詳細論述了連接體對兩塔樓動力特性的影響,對超長鋼結構連接體進行溫度應力分析、抗連續(xù)倒塌分析、豎向振動舒適度分析、施工模擬分析并且介紹了連接體關鍵節(jié)點的設計.根據(jù)結構特點采取了有針對性的加強措施.結果表明,各項指標均良好,結構能實現(xiàn)設定的抗震性能目標.
關鍵詞: 超限高層結構;復雜連體結構;豎向振動舒適度;抗連續(xù)倒塌分析

Abstract: The tower heights of the Dongxihui conjoined twin towers are 119 and 167.3m respectively,and the span of thehigh-level linker is about 70m. There is an angle between the two towers and between the tower and the connector. It is ahigh-rise large-span skew connected structure. The main twin towers adopt the frame-shear wall structure system and theframe-core tube structure system respectively,and the linker adopts steel truss system. According to the out-of-codecondition of the structure,the seismic performance design target was selected reasonably. The influence of the linker on thedynamic characteristics of the two towers was discussed in detail. The temperature stress analysis,anti-continuous collapseanalysis,vertical vibration comfort analysis,construction simulation analysis were carried out on the super-long steelstructure linker,and the design of the key joints of the linker was introduced. According to the structural characteristics,targeted strengthening measures were taken. The results show that all the indexes perform well and the structure can achievethe seismic performance target.
Keywords: out-of-code high-rise structure;complex conjoined structure;vertical vibration comfort;anti-continuouscollapse analysis
