摘要
针对某地铁站配套项目具有地铁隧道在地下室下穿、梁柱连接节点复杂,上部结构设有连接体、大悬挑等特点,梳理出该类项目结构设计的重点、难点及设计方法,并通过概念设计、方案比选、多模型多软件计算等方法进行相关研究分析。从研究分析可知,对于地下室厚板转换及复杂连接节点应进行有限元分析,对于上部设有连接体、大悬挑的地铁配套项目结构应进行抗震性能化设计、防倒塌连续设计和舒适度分析。
In view of the characteristics of a subway station supporting project,such as the subway tunnel passing under the basement,complex beam-column connection nodes,and the upper structure with connector and large cantilever,the key points,difficulties and design methods of this kind of project structure design were sorted out,and the related research and analysis were carried out through conceptual design,scheme comparison and selection,multi-model and multi-software calculation and other methods.From the research and analysis,it is known that the finite element analysis should be carried out for the basement thick slab transfer and complex connection nodes,and the seismic performance-based design,anti-collapse continuous design and comfort analysis should be carried out for the subway supporting project structure with upper connection body and large cantilever.
