Synopsis

Base isolation is one of the most powerful tools for earthquake protection of structures. The huge cost of conventional isolators makes them unaffordable for developing countries. The Scrap tyre pad isolator is an emerging low-cost technology for the seismic protection of structures. The tread portion of tyre can be cut into pads of definite size and arranged one above the other to form the isolator. In the present study, a G+7 storied structure isolated with scrap tyre pad isolators was analyzed using the response spectrum method in ETABS. The performance was also compared with that of conventional lead rubber bearings in terms of lateral displacement, drift ratio, storey accelerations, base shear and time period. The analysis results show that scrap tyre pad isolator is also effective in seismic protection of structures.
