| Description: | Miscellaneous Paper Abstract: Cyclic flexural fatigue tests were conducted on 6-by 6-by 36-in. fiber-reinforced concrete beams containing 0.5-in. and 1. 0-in. steel fibers to determine the change in ultimate flexural strength under fatigue loading. The beams were cycled at 3 Hz until failure occurred or 2 million cycles of load terminated the (45.22 percent) 1. 0-in. fibers tests. The beams with 0.5-in. fibers produced a smaller change in ultimate flexural strength than the beams containing (49.68 percent). The method of failure of the beams was by a gradual breakage of the bond between the steel and paste after the development of a crack in the concrete matrix, resulting in pullout of the fibers from the matrix. |
