Recommendations of RILEM TC 162-TDF Test and design methods for steel fibre reinforced concrete bending test

This test method evaluates the tensile behaviour of steel fibre-reinforced concrete either in terms of areas
under the load-def lection curve or by the load bearing capacity at a certain deflection or crack mouth opening displacement (CMOD)obtained by testing a simply sup- ported notched beam under three-point loading.

This standard is not intended to be applied in thecase of shotcrete.This test method can be used for the determination of:

– the limit of proportionality (LOP),i.e.the stress which corresponds to the point on the load-def lection or load

– crack mouth opening displacement curve (=>F(L) )defined in part 5 as limit of proportionality;
– two equivalent flexural tensile strengths which identify the material behaviour up to the selected deflection.
