Abstract
Base isolators are used as passive control devices for a structure during an earthquake. There are different types of base isolators which are used in a building. In this paper, a modified kinematic base-isolator is proposed based on human spine structure. The human spine works like a multilink inverted pendulum and uses different method to establish its equilibrium and stability. By using circumferential cables similar to ligaments and muscles and appropriate materials between two surfaces similar to intervertebral disk, it is possible to provide desired function for a base isolator. After modeling of the isolator, its behavior is derived and used for investigation of its effects on the structural behavior.
