The calculation of suspension bridge under vertical load is the most important content of suspension bridge design calculation and the most important basis of main component design. Combined with the knowledge of structural mechanics, this paper puts forward the elastic foundation beam algorithm, and deduces the important formulas for the cross-section design and strength comparison of sling, cable and stiffening beam. In use, as long as the parameters are brought into the formula, it is more convenient and fast compared with the complex software modeling. The method proposed in this paper is used to check the strength of the completed Japanese Guanmen bridge, and the results are accurate enough. It is fast and reliable to use this method in the preliminary design and rapid safety assessment of suspension bridge.
