An Experimental Study on the Stress-Strain Relationship of Steel Fiber Reinforced Conrete under Uni-Axial Compression Loading |
| Abstract |
With the increasing use of Fiber Reinforced Concrete as a structural material, More information on its physical properties is needed.This paper reports the results of experimental studies on the behavior of Steel Fiber Reinforced Concrete under monotonic and cyclic compressive loading.The results are that (1) SFRC does improve its compressive strength by the fiber volume fractions, the fiber aspect ratios and fiber diameters. Strength improvement with steel fibers ranged from 8.33 to 47.45 percent. (2)The fiber content to a concrete matrix produced a substaintial change in its stress-strain properties. This change is characterized by a significant increase in ductility as described by the descending portion of the stress-strain curve. The strain at the maximum compressive strength improvement with steel fibers ranged from 3.57 to 157 percent. (3) As compare with Plain Concrete.The cycluc stress-strain behavior of SFRC has a much stability. A higher fiber content produes a lesser steep descending portion, which results in a higher ductility of the material. |
