A study by the theory of elasticity leads to the conclusion that directly above a crack in a horizontal reinforced concrete beam the horizontal strains do not have a straight line distribution as assumed in the standard theory. Instead, the diagram of horizontal compressive strains or stresses may be drawn approximately as a parabola with apex at the end of the crack and with vertical axis. At the ultimate load the stress diagram may be approximately a quadrant of a circle. This suggests a theory. need for revision of the standard theory.
