Review Paper On Vibration Control Of Building Using Lead Rubber Base Isolator

Abstract

It has been widely seen that whenever earthquake occurs there is sudden shaking of earths surface due to the release of  large amount of strain energy.and the structure experiences shaking or vibrations and results in collapse. So, to overcome such hazard the base isolators is widely used.  Base isolator is the technique to reduce the vibrations of building which are provided at base. In this base isolator lead rubber base isolator is more effective. In Lead rubber isolator, lead core provides damping by deforming plastically  when isolator moves laterally. LRB may be represented through a bilinear model which can be characterized with three parameters the initial stiffness, post yield stiffness and characteristic strength..
