Abstract : The first phase of a study into the shear and bond capacity of high-strength reinforced concrete beams under static and dynamic load is reported. A static load test program involving midspan loads on two flexure and 11 shear beams with a 6-inch by 12-inch cross section and nine anchorage bond specimens containing numbers 8, 11, or 14S bars was conducted. Duplicate flexure specimens, shear specimens, and numbers 8 and 11 bar bond specimens were subjected to dynamic loading from a falling mass that struck each beam through an impulse-controlling cushion of vermiculite concrete. The concrete strength in the test beams varied from 6000 to 9100 psi. (Author)
