摘　　要：空间网壳结构为港口工程中大型煤棚常用的结构形式,因其明显的空间特性,常规设计手段无法满足计算分析要求。针对空间网壳结构的受力分析和设计问题,结合日照港石臼港区西区“散改集”工艺及环保提升项目的煤棚工程,采用通用结构有限元分析方法,从分析原则、结构选型、结构建模、作用和作用组合、结果后处理等方面进行分析。结果表明,采用正放四角锥双层圆柱面网壳、螺栓球网架节点、下弦支承的空间结构形式可满足工程使用要求,成果可为类似工程提供参考。Spatial reticulated shell structure is commonly used in large coal shed in port engineering.Due to its obvious spatial characteristics,conventional design methods cannot meet the requirements of calculation and analysis.In view of the analysis and design of spatial reticulated shell structure,combined with the coal shed project of the“transform bulk into container transportation”technology and environmental protection improvement project in the west area of Shijiu harbor district of Rizhao Port,the analysis principle,structure type selection,structural modeling,actions on structures and action combination,and post-processing of the results are analyzed by the general structural finite element analysis method.The results show that the spatial structure with the square pyramid double-layer cylindrical shell,the bolted spherical node and the lower chord support can meet the requirements of engineering.The results can provide references for the similar engineering.
