Introduction and knowledge of small production

The cable-stayed bridge, also known as diagonal tension bridge, is the main girder with a number of tension cables directly pulled on the bridge tower, a bridge is composed of a pressurized tower, tensioned cables, and bending beams group.
It is a kind of bridge which is composed of a pressure-bearing tower, tension-bearing cable, and bending-bearing girder.
It is a structural system that combines the tower under pressure, the cables under tension, and the girder under bending. It can be regarded as a multi-span elastic support continuous girder with tension cables instead of piers.

Sexually supported continuous beam, which can make the beam body bending moment reduction, reduce building height, and reduce the weight of the structure.

It can reduce the bending moment in the girder, reduce the height of the building, lighten the weight of the structure, and save the material. Cable-stayed bridges are mainly composed of cable-stayed towers, main girders, and cable-stayed cables.
Cable-stayed bridges are mainly composed of towers, main girders, and cable-stayed cables.

The main load of a cable-stayed bridge is not the cars or trains on top of it, but its own weight, mainly the main girders. Take a cable-stayed tower as an example. On the a-side of the towers are symmetrical cable-stayed cables, which connect the main girders of the towers together. Assuming that there are only two diagonal cables on both sides of the tower, one on each side of the tower, which is symmetrical. Left and right symmetrical each one, these two material Lazong by the main beam of gravity, the tower produces two symmetrical along the cable direction of the pulling force along the direction of the cable.

According to force analysis, the left side of the force can be decomposed into a horizontal to the left of a force and vertical down a force; the same right side. The force can be decomposed into a force horizontally to the right and vertically down a force: because the two forces are symmetrical, so the horizontal to the left and the horizontal to the right of the two forces are mutual
And horizontal to the right of the two forces cancel each other out, and ultimately the main gravity to become the tower of the two vertical downward force, so that the force is transmitted  To the piers below the tower. The number of diagonal cable and then more, the reason is the same. The reason why many articles, that is in order to divide the micro
The main beam to the cable-stayed force only
