A normal-weight plain concrete beam is 6 in. x 12 in. is simply supported on a span of 4 ft and is subjected to a midspan concentrated load of 4500 lb. Assume f’c = 3,000 psi, and concrete unit weight is 150 lb/cf. Calculate the maximum concrete tensile stress using both methods, and compare it with the value for modulus of rupture (fr) using the ACIrecommended value based on f’c.
