Abstract:
Results of tests of 32 rectangular concrete beams reinforced with four different types of high yield-point steels. The beams had an effective depth of I2 in., a width of I2 in. and a distance center-to-center of sup- ports of 9 ft. The four types of steel: ( I ) hard grade steel, (2) nickel steel (one beam only), (3) square twisted bars, and (4) twin-twisted and stretched bars, Results show that when a concrete beam is re-inforced against diagonal tension failure, the strength is determined by the total yield strength of the steel (steel area times yield-point stress) and not by the type of steel.
