The high-strength concrete deep beams exhibited more remarkable size effects with regard to brittle behavior. It was also shown that the ACI code gives similar safety factors on the shear strength at the first diagonal crack of high-strength concrete deep beams, but do not specify a high enough safety factor on their ultimate strength due to Cited by: Reinforced concrete deep beams are said to transfer heavy gravity loads predominantly through shearing action to their supports.

A significant characteristic of deep beams is their high shear. Get this from a library. Shear strength of high-strength concrete walls and deep beams.
