Abstract

A numerical analysis is presented for the determination of complete load-moment-curvature-deflection relationships for both short and slender reinforced concrete columns under combined biaxial flexure and axial load. The computer method developed can be used for any end conditions and variable section geometries such as circular and rectangular (solid and hollow), cellular, oval, channel and T-sections. Bending of the column is assumed to take place about principal axes of the cross section. The analysis takes into account an inelastic action and addresses all stages of behavior up to and beyond maximum load and moment. The method is also applicable to cases in which the cross section of the column is made up of different materials, where the cross section varies along the length of the column, and where prestressing and residual stresses are present. A comparison of the present analysis with experimental tests of biaxially loaded columns is examined. The computer analysis appears to show good correlation with experimental results obtained in this study, as well as those of others. © ASCE.
