Forty-two reinforced concrete beams were used in this testing- program. They were identical in size except for the percentage and grade of reinforcement. Thirty-six of the beams had only tensile reinforcement, the other six had two #4 bars in compression and two #5 bars in tension. Sixteen beams were tested to destruction under static load, the remaining P6 tested under impulse load. The load and reactions were recorded with a six-channel oscillograph and checked with a long-persistence-screen oscilloscope. The results indicated that the beams reinforced with high strength steel slightly outperformed the intermediate and structural grades. The capacity of various beams to absorb energy is covered in the discussion of test results. None of the reinforcing steel failed by snapping.
