STRENGTH AND DUCTILITY OF SQUARE REINFORCED CONCRETE COLUMN SECTIONS SUBJECTED TO BIAXIAL BENDING

The theoretical flexural strength of reinforced concrete columns with square cross section, with bending about a section diagonal and about a principal axis, are compared using the ACE Building Code (ACI 318-83) approach and a refined moment-curvature analysis that includes the beneficial effect of confinement of the concrete by transverse reinforcement. The results of experimental tests conducted on 400 mm (15.7 in.) square reinforced concrete columns subjected to axial load and to cyclic lateral load acting along a section diagonal are also presented. Test results are compared with those from similar columns tested previously with lateral loading acting along a principal axis of the section. The comparisons indicate that for the same quantity of confining steel and level of axial load, there is little difference between the flexural strength for bending about a section diagonal and for a bending about a principal axis. The available ductilities of the columns are also similar.
