摘　　要：生命港项目由6座主楼组成,各主楼通过顶盖连接。为满足建筑立面效果及使用要求,项目主入口位置上方的顶盖采用6根28 m高的钢柱框架结构;为减小钢梁及悬挑跨度,项目对钢柱进行分叉,并对结构的整体受力性能进行分析,验证结构的整体指标及构件强度是否满足规范要求;同时项目通过对结构进行屈曲分析、钢柱计算长度系数推算、整体稳定性分析、节点分析等,评价了结构整体及局部可靠性。The Life Harbor project consists of six main buildings,which are connected by a roof.Firstly,to meet the facade effect and usage requirements of the building,the roof above the main entrance of the project adopts a frame structure with six 28 m high steel columns.Then,to educe the span of steel beams and cantilevers,the steel columns have been forked,and the overall mechanical performance of the structure,and verify that the overall indicators and component strength of the structure meet the requirements of the specifications were analyzed.Lastly,the specialized analysis on key issues of the structure,including buckling analysis,calculation of the effective length coefficient of steel columns,overall stability analysis,node analysis,etc.have been conducted,which have evaluated the overall and local reliability of the structure.
