Elasto-plastic and collapse behavior of shear-deformable steel beam-column members are analytically examined, and especially, influence of the shear force on their plastic resisting capacity are considered and discussed. A new and effective hybrid stress finite element method/procedure, which are shown in Refs 3),4) and one of the most promising to trace the elasto-plastic and collapse behavior of the beam-column members and/or the frame structures, is employed. After conformation that the ultimate states of beam-column section have no dependence on the loading path, extensive and minute numerical tests are performed for the ideal elasto-plastic beam-column with the rectangular and the H-cross sections, and the plastic collapse characteristics and resisting capacity of the steel beam-column section under the axial forcing, the bending and the shearing are unifiedly investigated. Also, influence of the shear force on those are discussed and clarified.
