Abstract

A preliminary experimental investigation on the problem of viscous heating of fluid dampers that find applications in the vibration reduction of civil engineering structures is presented in this paper. Time histories of the temperatures are recorded near the piston head and at the outer surface of a 3-kip fluid damper that undergoes harmonic loading. The experimental results uncover some of the limitations of simple analytical expressions that have been derived in the past based on one-dimensional approximations of the energy balance equation.
