Introduction and knowledge of small production

Cable-stayed bridge (CABLE-STAYED BRIDGE), also known as a diagonally tensioned bridge, is the main girder with a number of
Cable pulling directly on the tower of a bridge, is by the pressure of the tower, pulling the cable and bending beams
It is a kind of structural system combined with a pressure-bearing tower, tensile ropes, and bending beams. It can be regarded as a multi-span elastic support bridge with cables instead of piers.
Continuous beam. It can reduce the bending moment in the beam, reduce the height of the building, reduce the structure’s weight, and save the material.

material saving. Cable-stayed bridges mainly comprise towers, main girders, and cable-stayed cables.
The main load the bridge bears is not the cars or trains above it, but its weight, mainly the main girders.
It is the main girder. Take a cable tower as an example, the two sides of the tower are symmetrical cable-stayed cables, which connect the main girder of the tower to the main girder.

The main girder of the tower is connected by diagonal cables. Assuming that there are only two diagonal cables on both sides of the tower, one on each side symmetrically, the two diagonal cables are connected by the diagonal cables.
These two cables are subject to the gravity of the main beam, the tower produces two symmetrical along the cable directions tension, the cable direction, the cable direction, the cable direction, the cable direction.
Cable direction of the tension, according to force analysis, the left force can be decomposed into a horizontal to the left of a force and a vertical downward force.
Force and a vertical downward force; the same right force can be decomposed into a horizontal to the right of a force
and vertical down a force; because these two forces are symmetrical, so the horizontal to the left and horizontal to the
The two forces to the right cancel each other out, and finally, the gravity of the main beam becomes the vertical downward force on the tower, so that, in this way, the main beam can be decomposed into a force horizontally to the right and a force vertically downward.
In this way, the force is transmitted to the abutment below the tower.
Cable-stayed bridges are bridges with a number of cable-stayed cables pulled on the tower columns. It consists of beams, cable, and
tower columns. Cable-stayed bridge is a self-anchored system, the horizontal force of the cable is borne by the beams
In addition to the beams on the piers, also supported by the tower columns lead to the cable-stayed. According to the beam used
According to the different materials used in the beams, they are divided into steel cable-stayed bridges, concrete cable-stayed bridges, and concrete girder cable-stayed bridges.

Precautions
Please check the materials before you start to make a cable-stayed bridge so that you don’t lose them and fail to make a cable-stayed bridge.
Children should be accompanied by teachers and adults to avoid injuries. It will be easier to succeed!
