How to select the floor and roof structure system according to the architectural characteristic is presented. The structure characteristic of main elements is analyzed. In the roof, the "arclr shell" combinatorial system is adopted, the arch and the latticed shell is linked with the latticed shell by V branch. The inner force of main structure is reduced by the indirect combination of floor and roof structure. The structure system of the project can supply reference for bigscale publi works, especially for elevated railway station
