It is often assumed that the post-crack ductility of Fibre Reinforced Concrete (FRC) and Shotcrete (FRS) is wholly defined by the result obtained in a standard flexural performance test such as ASTM C1609/C1609M or EN14651. However, the results revealed by these tests are only valid for the case of...
