What is a load-dispersing bridge?
Its superstructure is elastically supported at multiple points by rubber bearings to disperse the inertial forces of the superstructure and protect it from an earthquake. The following are some examples of such bridges.
Examples of the installation of LRBs and RBs
LRBs and RBs will be installed on an actual bridge as follows.
LRBs and RBs can be installed on all types of bridges, including concrete and rope bridges.
Bridge-Use Lead Rubber Bearing, LRB
Lead is press-fitted into a laminated rubber bearing to provide a seismic isolation bearing that dampens vibrations
Bridge-Use Rubber Bearing, RB
A bearing with alternating layers of rubber and steel plates that disperses horizontal force
Bingham Material-Stopper, BM-S
A cylindrical damper that uses the flow resistance of a special filler
