Abstract
A hollow beam structure such as a machinery subbase having apertures in sidewall portions thereof has a plurality of shear damper assemblies which straddle the apertures and are fastened to the wall portion on opposite sides of the apertures. The shear damper assemblies include a viscoelectric damping layer which dissipates vibrational energy to minimize the vibrational response of the hollow beam structure.
