Seismic Performance Analysis of Masonry Building with Scrap Tyre Pad Isolators

Earthquake has become a common natural hazard. The aftershock studies of recent earthquakes reveal that the effect of earthquakes is severe in low-rise masonry buildings too. Base isolation is an effective strategy to mitigate the effect of earthquakes on 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 masonry building model isolated with scrap tyre pad isolators was analyzed using the response spectrum method in ETABS. The performance was compared with that of masonry building without isolators in terms of lateral displacement, base shear and time period. The analysis results show that scrap tyre pad isolator is also effective in seismic protection of masonry structures.
