Several schemes of the reinforced concrete cross-beams were adopted and compared in the loottom plane design of a top floor indoor swimming pool. The distribution characteristics of the cross-beams as well as the prestressed concrete reinforcements were discussed in detail which has highly value for reference on similar cases. In addition, the analysis expanded solved the tough issues well in large-space and heavy-loaded structure designs.
