Abstract
A simple approach was developed for performance-based analysis of reinforced concrete columns subjected to shear, flexure and axial loads. This method is based on a simplification of a consistent but relatively more complex approach known as the axial-shear-flexure interaction (ASFI) method, which is able to predict the full load-deformation relationships of reinforced concrete columns subjected to axial, flexure and shear force. The uniaxial shear-flexure model (USFM), presented herein, can also predict comparable full load-deformation responses. In it, however, the computation-intensive iteration process for shear modeling used within the ASFI approach is eliminated and the formulation is simplified. This paper describes the formulation, implementation and verification of the USFM approach.
