深圳青少年活动中心复杂超限高层结构选型与分析

Selection and analysis of complex out-of-code high-rise structure of Shenzhen Youth Activity Center

深圳青少年活动中心属体型复杂且不规则的超限高层结构,设计时对大悬挑、桁架结构等特殊部位进行多种方案比较,探讨了结构方案调整的合理性及对结构工作性能和经济性的影响。对该超限高层建筑进行了结构弹性、弹塑性分析和针对一些不规则项的专项分析。结果表明,选取的结构体系是合理的,达到了既定的抗震设防性能目标。

Shenzhen Youth Activity Center is an irregular out-of-code high-rise structure with complex shapes. In the design,a variety of schemes of the large cantilever,truss structures and other special parts were compared. The rationality of the structural scheme adjustment was discussed as well as its impact on the structural work performance and economy.The structural elasticity,elastic-plastic analysis and special analysis of some irregular items were carried out for the out-ofcode high-rise building. The results show that the selected structural system is reasonable and achieves the established seismic performance target.
