Abstract:
A numercial method is developed for finding the moment at which the tensile reinforcement in a reinforced concrete beam will just reach the yield point if the beam is under-reinforced, or at which the concrete will reach its ultimate strain if the beam is over-reinforced. Curves are drawn of Al /bd 2 versus for a variety of assumed concrete stress-strain curves. he method is also applied to eccentrically loaded columns, and curves of yield load versus eccen-tricity (both in dimensionless form) are drawn for square, rectangular, and circular columns with a variety of per-centages of reinforcement and various assumed concrete stress-strain curves. The extension of this method to columns with bending in two directions is outlined.
