ASTM C469 provides a stress to strain ratio value and a ratio of lateral to longitudinal strain for hardened concrete at whatever age and curing conditions may be designated. The modulus of elasticity and Poisson's ratio values, applicable within the customary working stress range (0 to 40?% of ultimate concrete strength), are used in sizing of reinforced and nonreinforced structural members, establishing the quantity of reinforcement, and computing stress for observed strains.
