Abstract

Columns with axial load causing biaxial bending are present in many different building structures. The provisions of ACI 318 Section 10.2 are the basis for traditional design aids that show section strength when moments act in a plane of symmetry. Strength analysis for biaxial bending is significantly more difficult, as moments are not applied in a plane of symmetry. Several methods of analyses that use traditional design aids are reviewed and the results are compared with data obtained from physical tests of normal strength concrete columns subjected to short-term axial loads and biaxial bending. Results indicate that any among the four different methods of cross-sectional analysis are equally suitable for design purposes. The value of three-dimensional interaction diagrams in the design process is discussed. Computer-based methods of analysis are also described and compared with test observations.
