THE PROPERTY EXPERIMENTAL STUDY OF THE LATERAL AND VERTICAL COMPOUND SEISMIC ISOLATION SYSTEM

A kind of lateral and vertical compound seismic isolation system is proposed, and the model of test is also designed. The test is conducted in dynamic character, verifies the rigidity and damping properties of the model, it proved the theory of design. The property of the compound seismic isolation system is analysed in different frequency, the equilibrium position and amplitude; and the influences of disk spring and the lead rubber bearing are also discussed on the compound seismic isolation system. It is not only with vertical appropriate stiffness and damper performance, but also with stable performance and compact system, which is a good seismic isolation system as well.
