Abstract
A practical procedure for the geometrically nonlinear finite element analysis of in-plane beams structures is presented. The element stiffness matrix is obtained by superimposing the bending and the geometric stiffness matrices of elementary beam element and the stiffness matrix of linear bar element. A body attached coordinate is adopted to distinguish between rigid body and deformational rotations. The element internal nodal forces are calculated using the total deformational displacements. This formulation removes the restrictions of small nodal rotations between two successive increments. Numerical examples are presented to demonstrate the accuracy and efficiency of the proposed method.
