Abstract
This paper presents a beam-column model, based upon fiber-type, beam-column elements, for inelastic and large deformation analysis of planar steel structural systems. Derivations of the different stiffness matrices that are used in the model are presented. The model has the capacity to account for residual stress consideration. This model satisfies the rigid-body test while some of the other models do not. The accuracy of the model is compared to bench-mark problems via an example. The results indicate that the new model is more robust and has a faster rate of convergence for problems involving inelastic behavior, high stress, and large deflections.
