南京河西滨江G53项目4#楼异形悬挑钢结构设计

南京河西滨江G53项目4#楼,地上高度17.9米,钢结构框架,四根通高钢柱与屋面钢结构悬挑桁架组成主要的结构受力体系,结构布置不规则,结构受力复杂。采用不同的结构计算软件进行对比分析,保证模型准确性。设计时通过关键构件性能化设计、钢柱屈曲分析、节点细化设计等手段,增加结构整体安全度。

Building 4 of Nanjing Hexi Binjiang G53 project,with a height of 17.9 meters above ground,is mainly composed of a steel structure frame,with four through height steel columns and a roof steel as structural stress system.The structural layout is irregular and the structural stress is complex.Different structural calculation software is used for comparative analysis to ensure model accuracy.By means of performance-based design of key components,steel column buckling analysis,and refined node design,the overall safety of the structure is increased during the design process.
