A simple algorithm for the derivation of load-deformation relationships of a beam-column element is developed. Nonlinear beam-column element is modeled considering inelastic flexural deformations, geometric nonlinearities and elastic shear and axial deformations. In a frame structure, one element is used for one member that may be loaded by distributed loads. The distribution of inelasticity along the member is taken into consideration. The algorithm can be used not only in nonlinear static analysis but also calculation of the elastic stiffness characteristics of non-prismatic members such as haunches and tapered beams. Correlation studies with the existing literature have been conducted with the objective to establish the validity of the proposed algorithm.
