For hybrid fiber reinforced UHPC with two kinds of steel fibers, variation of the flexural behavior with different fiber distribution characteristics was estimated by experiments, and a prediction of the flexural behavior using smeared crack model. it was found that adopting a crack bandwidth considering the fiber distribution characteristics enable to predict the fractural behavior of UHPC beam.
