Two types of bar are commonly in use: " High yield steel bars with a yield strength of 460 N/mm2 (Grade 460). The ACI sets several limits regarding shear reinforcement to ensure that (1) sufficient shear reinforcement is provided to prevent shear failure (sufficient Vs), and (2) the shear reinforcement is distributed so that at least a sufficient number of bars cross the bottom-half of the shear crack (n bars every d/2). bar is in lightweight concrete.
