温州中心三塔连体超高层结构分析与设计
|
摘要
温州中心由一栋建筑高度280m和两栋建筑高度164m的超高层塔楼在140m左右的高空连接而成。介绍了温州中心结构设计要点,主要包括结构体系布置与效率分析、塔楼间连接方案选择、连接体对整体结构的影响及作用等方面,对连体结构支座布置与选型提出了一些针对性的分析方法和设计建议。分析结果表明,合理控制塔楼的扭转效应是确定连接方案时需重点考虑的因素。提出采用隔震支座串联单向滑动条块来实现高低塔楼之间弱连接的支座布置方案,使得整体结构满足抗风刚度要求的同时具备优异的抗震性能。
Wenzhou Center consists of two 160 m high towers and one 280 m high tower, which are connected one by one at the height of about 140 m. The key points of the structural analysis and design for Wenzhou Center were introduced, including the layout and efficiency analysis of the structural system, the selection of connection schemes between the towers, the influence and role of the connector on the overall structure, and so on. Some specific analysis methods and design suggestions were put forward for the layout and selection of connector bearings. The analysis results show that the reasonable control of the torsional effect of the tower is a key factor to consider when determining the connection scheme. It is proposed to use isolation bearings in series with one-way sliding plate to achieve a flexible connection between the high and low towers, and this innovative solution enables the overall structure to meet the stiffness requirements of wind resistance while providing excellent seismic performance.
