Shock Absorption Method Of Steel Trestle Of Bailey

The steel trestle has the characteristics of large structural steel degree and small deformation. It is widely used in highway Bridges. What are the damping methods of steel trestle trestle?

In order to reduce the seismic acceleration response of the structure, it is necessary to extend the natural vibration period of the structure to reduce the earthquake load. For the bridge structure, the use of rubber bearings, PTFE bearings and other sliding bearing namely tile to increase the flexibility of the structure, prolong the structure of natural vibration period. However, with the continuous extension of the natural vibration period of the structure, the relative displacement between the beam and pier also increases.

In order to reduce the relative displacement of beam pier due to the extension of the natural vibration period, the method of increasing the damping of the structure can be used. When the damping of structure is increased, the displacement response caused by earthquake can be inhibited obviously.
