Abstract: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-of-code high-rise building. The results show that the selected structural system is reasonable and achieves the established seismic performance target.
Keywords:complex out-of-code high-rise structure; structural selection and optimization; seismic performance design; dynamic elastic-plastic time-history analysis
