摘要: 三角咀产业园项目的塔楼与裙房之间通过跨度为 42m 的钢桁架连廊相连. 钢连廊与两侧主体结构之间采用抗震支座形成柔性连接. 主要从支座选型、结构静力分析、抗连续倒塌分析、罕遇地震下的变形计算、楼盖舒适度分析以及节点多尺度有限元分析等方面对钢连廊进行了设计与分析. 分析结果表明,该连廊的刚度、承载力以及支座变形均很好地满足相关规范要求,此分析方法对其他类似钢结构连廊工程的设计有一定的参考价值.

Abstract: The towers and podiums of Sanjiaozui Industrial Park project are connected by a steel truss corridor with span of42m. Flexible connection is formed between steel corridor and main structure by using isolation bearing. The design andanalysis of steel corridor were carried out from bearing selection, structural static analysis, progressive collapse resistanceanalysis, deformation calculation under rare earthquakes, floor comfort analysis and multi-scale finite element analysis ofjoints. The analysis results show that the stiffness, bearing capacity and bearing deformation of the corridor meet therequirements of relevant codes. The analysis method has certain reference value for the design of other similar steelstructure corridor projects.
