昆钢科技大厦结构高219.3m,采用矩形钢管混凝土柱的框架+型钢混凝土核心筒+伸臂桁架结构体系。结构利用设备层和避难层设置两道加强层(伸臂桁架+腰桁架)以提高结构的整体抗侧刚度。采用有限元软件对结构的关键部位和关键构件进行了精细分析,并进行了弹性和弹塑性动力时程分析,以落实抗震性能目标和多道抗震防线的实施。
Kunming Steel Technology Building, high-219.3m structure, the use of rectangular steel tube concrete column frame + steel core + boom tube boom structure system. Structure The equipment layer and the refuge layer are provided with two reinforcing layers (boom truss + waist trusses) to improve the overall lateral stiffness of the structure. Finite element software was used to analyze the key parts and key components of the structure, and the elastic and elasto-plastic dynamic time history analysis was carried out to implement the seismic performance target and multi-channel seismic defense.
