The influence of fibre orientation on the post-cracking tensile behaviour of steel fibre reinforced self-compacting concrete

A. Abrishambaf, V.M.C.F. Cunha, J.A.O. Barros

Adding fibres to concrete provides several advantages, especially in terms of controlling the crack opening width and propagation after the cracking onset. However, distribution and orientation of the fibres toward the active crack plane…
