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.
