深圳湾创新科技中心超高层连体结构性能化设计
|
摘要
深圳湾创新科技中心超高层连体结构为两道连接体相连的两栋超高层塔楼2A,2B,为非对称双塔连体结构。两塔楼在低区(6~9层)、高区(34~37层)通过两个跨3层高的连接体连接为一体,连接体采用钢桁架结构。首先介绍了本项目的概况、结构体系、结构超限判别、抗震性能目标,然后介绍了性能目标验算结果、连体桁架分析、跃层柱稳定性分析、大震下抗震性能评价和结构抗震加强措施。分析结果表明,结构各项指标均满足规范及性能目标要求。
Shenzhen Bay Innovation and Technology Centre super-tall connected structure is composed of two super high-rise tower buildings 2A and 2B that are connected by two connective bodies. It' s an unsymmetrical twin-tower connected structure. Two tower buildings are connected as a whole by two 3-layer high connective bodies at 6 ~ 9 layer of lower zone and 34 ~ 37 layer of higher zone,and the connective body adopts steel truss structure. The project general situation,structural system,structure out-of-code discrimination and seismic performance objectives were first introduced,and then the checking results for performance objective,analysis of the connective truss,stability analysis on skip-layer column,seismic performance evaluation under rare earthquake and seismic strengthening measures. The analysis results show that all the structural indices meet the requirements of specifications and performance objectives.
