Abstract:The main structure of the lower part of Ninghai Convention and Exhibition Center adopts reinforced concretestructure,and the area with large span and heavy load adopts steel-concrete composite structure. Considering thearchitectural shape,tree-shaped concrete columns were used in the large span to optimize the force,reduce the section andsave the cost. Due to the complex shape and large span of the roof,it adopts a three-dimensional complex special-shapedsurface steel structure system and a single-layer three-way box-section steel reticulated shell structure. A variety of finiteelement softwares were used to analyze and compare the overall and local components of the structure,and finally the safetyof the structure was ensured through the envelope design of the calculation results. The calculation results show that thedesign of the tree-shaped concrete column and the special-shaped surface steel reticulated shell can meet the correspondingrequirements of the specification. On the premise of ensuring the modeling effect of the building facade,it not only satisfiesthe safety of the structure,but also takes into account the economic rationality,which realize the beauty of structureachievement architecture.

Keywords:Ninghai Convention and Exhibition Center;steel-concrete composite structure;tree-shaped concrete column;large-span steel structure roof;special-shaped surface steel reticulated shell
