Experimental Evaluation of Compression Properties of Reclaimed Rubber Base Isolator
Traditional rubber seismic isolators are rarely employed for residential buildings as they are big in size, heavy and expensive. Fiber reinforced elastomeric isolators (FREIs) have been identified to provide cost effective base isolation. In this paper, base isolators are developed using reclaimed rubber reinforced with carbon fiber reinforcement polymer (CFRP). Vertical stiffness of the isolator is determined experimentally. Isolators with 4, 6, 8, 10 11 and 12 layers of reclaimed rubber pads with and without CFRP reinforcement are considered in the study. Effect of aspect ratio on vertical stiffness is also investigated.
