| Abstract: | This paper studies a precise computing method and applies to a suspension bridge.From the balance of the structure internal force,it finds the deflection,the moment and the shearing force of the beam expressed by the horizontal tension Q of the main cable.The undetermined constant A and B are solved using the bound conditions,then the displacement equation is established and the formulation of the horizontal tension Q is found.Finaly the Q is solved using iterative method. |
