Results of Loss Factor Measurements on Steel and Concrete Beams Using a Viscoelastic or Sand Damping System

Abstract

The results of tests to measure loss factors on steel and concrete beams using a viscoelastic or sand damping system are discussed. The significance of the tests using the viscoelastic material was the rather large size of the system; for the sand damping system, data was obtained at frequencies down to 36 cps. Numerous configurations are tested. For the sand damping case, loss factors are measured as a function of acceleration.
