Fatigue Behavior of Steel Fiber Concrete in Direct

An investigation was conducted to study the behavior of plain concrete and steel fiber reinforced concrete under direct tension fatigue loading. Tests were conducted on dogbone specimens with varying amounts of steel fiber volume content (0, 0.75, and 1.5%). A new concept was introduced in deriving material damage parameters for plain and steel ...

2002-4-1  Yin and Hsu reported the effects of steel fibers (fiber content of 1%) on the compressive fatigue life of concrete finding that the addition of fibers increases the fatigue life of concrete for stress levels above 0.70. However, these tests are somewhat different since the test specimens are plates (150×150×38 mm 3) sawed from blocks.

2000-5-2  The influence of steel fibers on the fatigue resistance of concrete in direct compression, based on experiments, and an assessment of it through neural network modeling have been presented. Both straight and hooked fibers were incorporated in the concrete. The volume fraction was 1% for straight fibers, and both 1 and 2% for hooked fibers.

Fatigue life prediction of fiber reinforced concrete

1999-11-1  For steel fiber reinforced concrete the S–Log(N) curve becomes curved. Second, the present model predicts that the steel fibers can significantly improve the bending fatigue performance of concrete structures, which has been demonstrated by many researchers , , , , . For steel fiber concrete beams, with maximum flexural stress between 9.00 and 10.00 MPa (level III), the fatigue life of SFRC is very

The fatigue strength and behavior of plain and fiber concrete are investigated. Seventy-two steel reinforced concrete specimens, with 1 volume percent of 25-mm (1-in)-long fibers, were tested under compression fatigue loading. The S-N curves were obtained under four stress ratios of 0 (uniaxial), 0.2, 0.5, and 1.0, resulting in a series of fatigue stress envelopes for fiber concrete.
