Equivalent-Beam Theory of the Self-Anchored Suspension Bridge
Taking one typical two-tower three-span self-anchored suspension bridge as an example, structural response has been characterized in detailed followed by its own construction steps. Meanwhile, the structure’s mechanics properties have been mathematically formulated through theoretical analysis method. Finally, the formulation has been further expressed by using a simplified beam subjected to external equivalent forces, and then the equivalent-beam theory of the self-anchored suspension bridge has been well established thereafter. As been demonstrated, the equivalent-beam theory can be easily and clearly applied to determine the vertical mechanical properties of the self-anchored suspension bridge, and could be utilized to guide the self-anchored suspension bridge deign in the future.
