Seismic Design of Resilient Sliding Isolation System for Protection of Equipment

Parimal P. Dhote, Amey Khedikar


Seismic isolation is one of the high-quality options to defend equipments. It allows manipulating reaction acceleration transmitted to gadget under its allowable stage. Amongst several sort of isolation machine, the combination of restoring spring and slider (resilient sliding gadget) is a very powerful device for protection of equipment. In design of this sort of isolation system to make certain functions of equipments, there are many appropriate mixtures of stiffness and friction coefficient. But on the same time it is also essential to govern relative displacement of isolation system so as to offer safety to the connections of gadget with other structures like energy deliver, major servers and so on. This have a look at offers with most excellent design of equipments with those resilient sliders which could manage acceleration underneath allowable stage and at equal time decrease the relative displacement. Ideal parameters of resilient sliding isolators are determined analytically for different degrees of allowable acceleration. The validity of analytical technique used, is also proven by shaking table checks. Effects of this examine display that 1) most desirable values of period are decreased with increase of allowable acceleration    2) The most excellent friction coefficient is elevated with higher allowable acceleration.
