The impact resistance of reinforcing steels of vari- ous grades was investigated by tests on IO x I6 in. beams on a span of 8 ft, reinforced with varying amounts of steels of different grades. These tests indi- cate the great value of even small amounts of rein- forcement in beams subjected to impact, the enor- mous reserve against collapse after the yield point of the reinforcement has been passed, and the fact that, within the limits of the tests, when subjected t o energy loads even more severe than are likely to be met with in practice no noticeable difference in strength was sh’own by beams reinforced with different grades of steel.
