Details of Bolt Rocker Bearings

This type of bearing can perform universal rotation and bearing for the transmission, rotation and movement of the reacting forces caused by different loads on the superstructure, such as the constant load, living load, wing seismic force, etc., and make sure the reacting forces and resultant force are concentrated, explicit, safe and reliable.

　 This type of bearing can bear the tensile, compression and (lateral) shear. Under the huge random seismic force, no disastrous damage like the falling of beams or support, which is a common case for bridges with ordinary bearings, will occur with this bearing as long as there is no damage in the superstructure or substructure itself. The strength and ductility of this bearing are even higher than the structure itself, and it can resist the seismic intensity up to 9 degrees, so it is particularly applicable in areas with high intensity earthquakes.
