The present paper deals with some crucial design aspects of Fiber Reinforced Concrete (FRC) beams under shear loading, with or without conventional transverse reinforcement. It focuses on shear critical beams made of plain concrete or FRC. The influence of fibers on crack formation and development, failure mode, ductility and stiffness are herein investigated. A recent analytical proposal of the authors is further de-veloped. Statements on the minimum shear reinforcement provided by steel fibers are derived and discussed. Finally, some preliminary results on the size effect issue of FRC members in shear and a design example are reported.
