Database with shear tests on steel fibre reinforced concrete girders

The application of macro fibres made of steel is recently -growing in concrete engineering since valid standards like the DAfStb-Guideline "Steel fibre reinforced concrete" of the German Committee for Structural Concrete (DAfStb) are available. In particular, it is meaningful to take into account fibre's effect in shear design to considerably reduce the amounts of stirrups. The most significant parameter is the steel fibre's post-cracking tensile strength that exhibits pronounced scattering due to several interacting parameters. It is differently considered in the design approaches of DAfStb-Guideline and fib Model Code 2010, respectively. The paper investigates accuracies of predicted shear resistances by comparing calculative and experimental ultimate loadings. For this purpose, a shear database is build up comprising more than 250 test results from the literature that differ in cross-section's geometry, ratios of longitudinal rebars and stirrups, fibre amounts and concrete compressive classes, respectively.
