Assessing The Dead Loads Effect on the Dynamic Behavior of Plates by Using Finite Elements Method

Abstract

In this research, a rectangular plate element for the finite elementsmethod, which takes into consideration the effect of dead loads, is proposed.The element stiffness matrix that includes the effect of dead loads is derived. Itis shown that the stiffness of plate increases when the effect of dead loads isincluded in the calculations. The validity of the proposed method is confirmedby numerical example and the results show a good agreement when comparedwith that obtained from the closed-form solutions. The proposed methodbased on a finite elements formulation is more easily applied to plate’sstructures under different support conditions and various types of dead loads
