DYNAMIC ANALYSIS OF FRAME AND PLATE STRUCTURES WITH GEOMETRIC AND MATERIAL NONLINEARITIES

The objective of this study was the development of a procedure for determining the large dynamic response of structural systems consisting of beam and rectangular plate elements. The analysis takes into account both geometrical and material nonlinearities. The general approach to the problem is based on the finite element method and the use of displacement interpolation functions. The strain energy expressions for both the beam and plate elements are obtained and are used to generate the stiffness and mass matrices of the elements. Also, the geometric stiffness matrices are derived which account for the effect of geometric nonlinearities. Plastic deformations are taken into account by means of an incremental theory of plasticity coupled with the concept of initial strain. (Modified author abstract)
