A three-demensional space structure is often treated as a collection of two-dimensional planar structure, and the members in a planar frome are designed to resist bending moments acting in the plane of the frame. In an actual building framework, the columns are frequently subjected to bending moments acting in two perpendicular directions in addition to an axial load, which is commonly called biaxial loading. In this paper, an analytical procedure is presented for the determination of the ultimate carrying capacity of columns of H-shaped cross section subjected to biaxial bending. The method of analysis is based on the incremental load procedure. In this paper, the elasto-plastic behaviour of the column subjected to biaxial bending under the constant axial load is also presented, and the effect of the warping restraint at the end cross section on the elasto-plastic behaviour of the column is illustrated.
