This presents a summary of analysis and design of seismic isolation system by energy mitigation with LRB on bridges.Join a company that is passionately committed to the pursuit of a better world through positive change. Therefore, this represents substantial reduction in cost because of reduction of expansion joint. Most of all, total displacement on design for all LRBs case is reduced comparing with combined lead-rubber and elastomeric bearing system.

Design forces, displacements, and drifts are given distinctive consideration in accordance with Caltrans Seismic Design Criteria (2004). It is expected that example is developed for all Lead-Rubber Bearing (LRB) seismic isolation system on piers and abutments which placed in between super-structure and sub-structure.
