摘要：In this paper, the performance verification study on a recently developed vertical vibration isolator is presented.The vertical seismic isolation system consists of four wedge-shape steel parts which provide friction surface at their interfaces, a center and two side springs, and a lateral bar which functions as a guide to side springs.The theoretical model for the isolator derived from the force equilibrium relationship is verified via numerical analyses and prototype tests.The performance of the isolator is further verified using the shaking table test.The analytical and experimental studies show that the isolator can reduce the vertical vibration effectively.
