Optimized Design of Beam Depth for Prestressed T Beam Jointless Bridge;

In this paper,some laws about the influences of beam depth on flutter stability of suspension bridges are drawn by empirical formulas and FEM,and an approximate formula of design of beam depth of suspension bridges with a fixed width is proposed.

Combined with the specific engineering,the design of single span 40 meters portal steel structure bridge was introduced,the smaller beam depth and vertical,inclined piece dimension effective on the portal steel structure inner force.
