Influence of Aspect Ratio of Hooked End Steel Fiber on Flexural Behavior of Fiber Reinforced Concrete

Abstract:

The aim of present work is to further investigate the flexural behavior of FRC with four types of hooked end steel fibers. The flexural toughness of FRC beams was tested under a three point bending system, and the data of experiments were analyzed according to the standard JGJ/T221-2010 and RILEM recommendation. The results showed equal dosage of different aspect ratio fibers didn’t result in the same flexural toughness. It was found that nominal ultimate flexural strength () and equivalent flexural strength () of beams increased as aspect ratio of the steel fiber was increased. However, the highest equivalent flexural strength () was obtained by the fiber with aspect ratio of 67.
