Abstract
A bi-directional rolling pendulum seismic isolation system for reducing seismic force acting on a structure by rolling pendulum movements, the system having a lower plate forming a rolling path in a first direction; an upper plate forming a rolling path in a second direction; and a roller assembly performing a pendulum motion by rolling and moving along the lower and upper plates wherein the roller assembly performs the pendulum motion when seismic load is applied, thereby reducing the seismic load of a structure.
