The enhancement of seismic performance is the main concern of owners and designers in the use of elastomeric bearings for the performance criteria. The LRB (Lead Rubber Bearing) and the HDRB (High Damping Rubber Bearing) are widely used as a part of the base isolation systems (BISs). This paper discusses and investigates the difference between them for their seismic performance and their effects for deduction of structural weight and material usage for the low-rise and mid-rise structures. The results show that the HDRB has better seismic performance in conjunction with its efficiency for weight deduction which conducts the projects for an economic design. Conclusion of paper shows clear vision to design engineers for future selection between LRB an HDRB BISs.
