LRB, BM-S and isolation damper can be applied to movable piers of rigid and flexibly supported bridges to disperse seismic force on them and to reduce the load on rigid piers.
LRB,BM-S and isolation damper can be selected with resistance characteristics suitable to the yield strength of the movable pier.
High performance in energy absorption of LRB, BM-S and isolation damper markedly reduce seismic force transferred to a structure and restrict displacement. Aseismic retrofit without replacement of existing bearings is also possible.
