  FRC precast segment characteristic residual flexural strength dertermination

  A number of large tunnels have already been built around the world with Fibre Reinforced Concrete (FRC) precast segment linings.In accordance with fib bulletin 83, Model Code 2010, the structural design of FRC elements is based on the post-crack residual tensile strength provided by the steel fibers. Nominal values of the material properties can be determined by performing a flexural bending test.
