[EN] The shear strength of elements reinforced by fibres is predicted by Codees using formulations generally developed from a limited set of test results.
Characterisation of the tensile behaviour of UHPFRC remains a challenge for researchers, and an
agreement on the standard test set-up and advisability of notch is yet to be reached. Bending tests are
easier to conduct ...
