Installation steps for bearings for prefabricated multi piece T-beam bridges

Materials and performance of seismic isolation bearing : The materials and performance of seismic isolation bearings directly affect the LRB service life. For example, seismic isolation bearings made of rubber materials, like lead rubber bearing, high damping rubber bearing,they have the characteristics of high damping,

Compared to traditional sealing methods, such as welding or installing piston valves, it is easier to plug air bags with pipes.

After summarizing experience in designing, manufacturing, and using spherical bearings over the past decade. We have referred to the design method for spherical bearings specified in the European standard EN1337 and used finite element analysis to optimize the design.
