The large deflection behavior of spatial rigid frames is analyzed on the basis of the beam-column finite element method using the incremental perturbation technique. A beam-column finite element model is composed of several fiber segments. The numerical results predict with good accuracy the experimental load-deformation curves of the frames subjected to monotonic or cyclic horizontal force under constant vertical load. It is verified that the proposed method of the analysis is effective in the overall range of the large deflection behavior including the critical behavior and deteriorating behavior.
