Abstract
A study is presented of the potential of constrained viscoelastic layers in enhancing the damping of two-way slab floor systems with simply supported and clamped boundary conditions subjected to dynamic loading. The finite strip method is extended to the analysis of the resulting sandwich structures. The damping of the sandwich system is mainly due to the shear deformation of the viscoelastic layers and is described by a composite loss factor. Results are presented which demonstrate the effect of the elastic, damping, and geometric properties of the attached layers as well as their location in the domain of the slab, on the damping of the structures considered. Substantial damping can be achieved by proper choice of these parameters.
