Structural design of fibre-reinforced members should take into consideration fibre orientation since the residual properties of the material can be different as a function of the cracking plane position and inclination. Designers must be aware of the possible negative influence of fibre orientation and they may take advantages from its positive effect. Some international standards (i.e., fib Model Code 2010 and German standard DafStb) define a factor that should take into account the orientation effects. In this context, the present paper presents the results of an experimental program aimed at evaluating steel fibre orientation in RC beams. Three beams (0.15 m x 0.70 m x 4.10 m) were cast at Magnetti Building (Carvico, Italy) factory following the most common casting process adopted in practice by using vibrated and self-compacting concrete.

Abstract
Structural design of fibre-reinforced members should take into consideration fibre orientation since the residual properties of the material can be different as a function of the cracking plane position and inclination. Designers must be aware of the possible negative influence of fibre orientation and they may take advantages from its positive effect. Some international standards (i.e., fib Model Code 2010 and German standard DafStb) define a factor that should take into account the orientation effects. In this context, the present paper presents the results of an experimental program aimed at evaluating steel fibre orientation in RC beams. Three beams (0.15 m x 0.70 m x 4.10 m) were cast at Magnetti Building (Carvico, Italy) factory following 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.
