Abstract:
Seven pretensioned concrete beams were subjected to a highly impulsive load. The load, reaction, and displacement of the member were recorded. A comparison is made by determining the ratio of ultimate dynamic moment to ultimate static moment. The test results show that the members will carry a 35 percent larger ultimate moment when applied dynamically.
