| Abstract: | Neste trabalho, são apresentadas duas formulações consistentes de elementos finitos, para análise não-linear geométrica de pórticos tridimensionais. Na primeira, a discretização é feita através de um elemento de eixo reto e seção transversal constante, que interpola os deslocamentos utilizando as funções convencionais de pórtico. Na segunda, o elemento, de eixo curvo e seção transversal variável, é resultante da degeneração do elemento isoparamétrico tridimensional. |
| Abstract: | In this work, the finite element method is applied to problems involving the geometrically nonlinear behaviour of framed structures. Two consistent formulations of three-dimensional beam element are presented. In the first one, the element is straight with constant cross section and the displacements are interpolated by the usual beam functions. In the other one, the element is arbitrarily curved in space with variable cross section and results from the degeneration of the three-dimensional isoparametric element. |
