|Abstract:||A study was carried out to investigate the cyclic behavior of steel-fiber cement-mortar overlaid concrete beams at various stress levels. Two different volume fractions of steel fibers were selected for the present study. The concrete-beam specimens used in this study were tested simply supported with a point load at midspan. Two different types of bonding conditions were studied. The deterioration in the flexural rigidity of the test specimens after being subjected to a predetermined number of load cycles was evaluated. The test specimens were subjected to 100,000 cycles of loading under a maximum load of 45, 55, and 65% of the ultimate static load. Static loading tests to failure after 100,000 cycles of applied load showed that some of the beams loaded up to 65% of ultimate static failure strength failed by partial or complete delamination of the overlay. The results of the experimental tests are summarized and discussed in this paper.|
