Abstract
The design of structural elements should take into consideration fiber orientation since the residual properties of the material can be different depending on the fiber inclination with respect to the cracking plane. The “orientation factor” should represent the different post-cracking performance present in a real structure due to a fiber orientation as compared to the ones obtained from standard tests. In this context, the present paper presents the results of an experimental program aimed at evaluating steel fiber orientation in RC beams. Several beams (0.15 m x 0.70 m x 4.10 m) were cast at Magnetti Building (Carvico, Italy) manufacture fol-lowing the most common casting process adopted in practice by using vibrated and self-compacting concrete.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
