Abstract

Flexural performance data obtained from beams are used widely in the design of fiber-reinforced concrete (FRC) structures. However, loading configurations under which a material is expected to perform in situ seldom match the third-point loaded beam used in tests on FRC. In the present investigation, the performance of FRC beams tested using third-point loading have been compared with nominally identical beams tested using central point loading. The results indicate that the Modulus of Rupture obtained using third-point loaded beams is lower than that obtained using centrally-loaded beams but that the post-crack performance of the former is greater.
