Abstract
A conventional rate-dependent damper is equipped with a relief valve to restrict an excessively large damping force being generated regardless of the response displacement. The equivalent damping coefficient deteriorates when the ground motion is severe and the relief valve is activated, whereas the damping coefficient is kept large when the input ground motion is moderate and the relief valve is inactive. In this paper an ideal rate-independent damper is proposed that generates a damping force according to the response displacement for the effective displacement control in a base-isolation system. Comparisons with base-isolation systems containing conventional rate-dependent dampers and rate-independent dampers illustrate the effectiveness of the proposed damper for the reduction of floor response acceleration without deterioration of the response displacement.
