RESUMO
Throughout this thesis the formulation of the mathematical modelo f a general tri-dimensional beam element with reduced degrees-of-freedom is presented. The element is a four node displacement based finite element with three linear and one locally referrer rotational displacements at each node. Bending effects are taken into account through the imposition of non-transversal shear condition. Coupling between adjoining elements anda t the element clamped restraint is asssured by a penalty procedure imposed at the common node location. The analysis of some simple structures are presented and the solutions compared with other analytical or numerical results. The formulation hás been proposed so that it can be generally extended to material non-linear and dynamic analysis.
