Cable-stayed bridge is a kind of bridge that directly pulls the main beam on the bridge tower with many cables. It is a kind of structural system combined by the tower under pressure, the cable under tension and the beam body under bending. It can be regarded as a multi-span elastic supporting continuous beam with cable instead of pier. It can reduce the bending moment inside the beam, reduce the height of the building, reduce the weight of the structure and save the material. Cable-stayed bridge is mainly composed of cable tower, main beam and cable. Also have Footbridge that is an asymmetric, cable-stayed, pedestrian swing bridge whose form and function was dictated by site constraints.

Specification:

Cable-stayed bridge is a bridge with several cable-stayed beams on the pylon. It consists of three parts: beam, stay cable and column. Cable-stayed bridge is a self-anchored system in which the horizontal force of the cable is borne by the beam. The beam is supported not only on the pier but also on the cable drawn from the tower. According to the different materials used in the beam, it can be divided into steel cable-stayed bridge, combined beam cable-stayed bridge and concrete beam cable-stayed bridge.

Cable-stayed bridge structure belongs to high order statically indeterminate structure in mechanics, which is the most complex structure in all bridge types. Because of the different cable forces and construction methods, the final stress state of the bridge will be obviously different. Therefore, in the force analysis of cable-stayed bridge structure, the primary task is to determine the reasonable bridge state, so as to make the bridge structure uniform force, and then determine the reasonable construction state.
