ABSTRACT

This paper deals with dynamic characteristics of new type high-viscous damper developed by CKTI-VIBROSEISM whose dynamic characteristic can be changed by the viscosity of liquid, the number and dimension of shells. The applicability of this high-viscous damper was very high by the vibration test of 6" three dimensional piping model and seismic Isolation Floor System using a shaking table. The large damping effect of CVS Damper have been shown through test and the experimental results agreed well with analytical one.
