Title: Ultimate Flexural Analysis Based on
Stress-Strain Curves of Cylinders

Abstract:Describes a stress block for ultimate loed analysis based upon the stress-strain relation of G x 12-m. cylinders. The stress-strain relation from a cylinder, which includes a decrease in stress beyond the ultimate, is described by a single continuous function. The function is used to compute the total com-pressive force in the compression zone, position of neutral axis, and ultimate moment. The computed values of total compressive force, neutral axis location, and ultimate moment are compared with actual test values of rein-forced concrete beams. The mode of failure is predicted for beams of near balanced design. The approach described leads to a more accurate analysis of beams reinforced with more than one layer of steel.
