Abstract

Presents an iterative procedure to perform the exact design of arbitrarily shaped reinforced concrete members against a combination of axial force and biaxial bending moments. The suggested method is believed to be divergence-proof and is capable of handling sections with reinforcement layout so unsymmetrical that the origin of the Mx-Myreference axes falls outside the iso-load contour corresponding to the applied axial load. The rate and reliability for convergence in this method make it suitable for use in practical design. Oddly shaped concrete sections commonly adopted in bridge abutments and core wall systems can be handled, and the minimum steel area required in resisting the design loadings is determined. This leads to a more economical and safer design for reinforced concrete structures.
