Effect of Fiber Properties on Mechanical Properties of Steel Fiber Reinforced Concrete under Uniaxial Tension and Shear

The post-cracking behavior of a steel fiber reinforced concrete is important because it affects the crack width which influences the durability of the structure. In this study the deformational behavior of a steel fiber reinforced concrete subjected to uniaxial tension and shear was investigated experimentally by applying a load to a specimen with a discontinuous plane for a crack. In the experiment the effects of the fiber inclining angle to the crack plane and the fiber geometry were investigated. High-strength concrete was used in the specimen. From the experimental results models for load-displacement relationships were obtained considering the fiber inclining angle as a parameter.
