Abstract

The presented paper examines the performance of the Allman's membrane as a supplementary membrane element for geometrically nonlinear analysis of shell structures. The examination is based on an original formulation that is presented in this paper as well. The presented shell element is comprised from the Allman's membrane element and the discrete Kirchhoff theory (DKT) plate element. These elements were upgraded to perform geometrically nonlinear analysis by means of additional geometric stiffness matrices. Finally a computer program was coded to perform the analysis and three problems mentioned in the literature were chosen to study the performance of the presented shell element.
