    Abstract

    A new dissipation element is introduced which utilizes Coulomb friction to `brake' horizontal building motions. The device resembles a classical impact damper but avoids impact-induced, detrimental accelerations. The reduction of structural response, due to the addition of Coulomb damped masses, has been studied by computer simulation. Results, obtained from the analysis of single degree of freedom oscillators subjected to harmonic base motions, look promising. Over a broad range of excitations, the Coulomb damped masses yielded reductions in structural response. The devices were particularly efficient after the first initial seconds of motion.
