Vibrations of Simply Supported Orthotropic Rectangular Plates Reinforced by an Intermediate Beam Support

Abstract

Free, forced and transient vibrations of simply supported orthotropic rectangular plates are numerically studied. The plate is supported by a beam parallel to the side of the plate through a damping material, whose properties are modeled by the finite number of discrete springs and dashpots. The effect of the number of supporting points and the flexural rigidity of the beam on the dynamic behavior of the plate is clarified. Furthermore, the possibility of the reduction of vibrating plate deflections is discussed.
