Slabs are concreted complete with ducts and openings framed with metal aprons welded to slab reinforcement and intended to accommodate columns. 楼板用混凝土浇注成整体，其上留有用金属挡板围成的孔道和提升环，它们和楼板配筋焊接在一起，以备将柱子套入其中。
Based on the proposed formulas and the results of the finite element analysis, the quantity and arraying of the reinforcement bars in the platform are obtained. 并以此为基础，根据对预应力混凝土平台罐体的有限元分析结果，进行了配筋设计。
