Abstract

In this study, numerical analyses demonstrate that a simple symmetrical 3D steel moment resisting frame with slight eccentricity can exhibit torsional behaviour despite a diagonal load being applied in a perfectly symmetrical manner. The torsion may be caused by inelastic bifurcation buckling, where the combined effect of the material and geometrical nonlinearity plays an important role. The similarities between this phenomenon and the inelastic buckling theories found in the literature are discussed.
