Current tests on the bond strength of reinforcing bars in high strength concrete beams may result in the revision of the American Concrete Institute's code restrictions on the use of such bars. It is expected that it will limit the development strength of concrete beams in excess of 10,000 psi to only that of 10,000 psi. To evaluate bond capacity, beams with strengths up to 18,000 psi are tested to destruction. Engineers are looking for beam capacity, strains in the reinforcement, crack development and beam deflection, among other aspects of performance. Variables in the tests include the size of the rebar, the amount of cover over the rebar, and the lapsplice length.
