PLASTIC DESIGN OF BIAXIALLY LOADED BEAM-COLUMNS.

Abstract

The paper presents a design technique for determination of the maximum plastic strength of biaxially loaded beam-columns which makes it possible to calculate the maximum compressive load that a column can accept while subjected simultaneously to bending moments about both of the principal axes. The analytical procedure is based on an equilibrium technique in which the external forces acting on the cross section are equated to the internal resistances of that section as determined by the distribution of longitudinal stresses.
