Steel Fiber Reinforced Concrete – Shear Strength

This paper present experiments which aim to measured steel fiber reinforced concrete beams shear strength. We present three of among can be found in the literature, with the proposed equations, based on the experimental results, to define a fiber reinforced concrete element shear strength. An important input parameter of the equations is the τf bond strength between fiber and concrete. We present from the literature straight, hooked-end and crimped steel fiber pull-out test. The value τf is important by the calculation of the load bearing capacity from shear of beams.
