【摘要】 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。更多还原

【Abstract】 The height of Kungang Technology Building is 219.3m,the concrete-filled steel column frame and concrete-encased composite corewall and outrigger truss system is adopted.To enhance the lateral-force-resisting stiffness,owtrigger trusses and belt trusses are used at mechanical story and refuge story.The key parts and key members were precisely analyzed by finite element software.Elastic and elastic-plastic time-history analysis were provided to implement the seismic performance objective and multi-line to defend earthquake.更多还原
