Abstract [en]

This paper presents findings from a study on punching shear capacity of high-performance concrete slabs reinforced with macrobasalt fibers. The punching shear failure is simulated through a simple method introduced by Hassan et al. The test specimens comprised 14 small-scale slabs with circular notches. To investigate the effect of fiber content, 5 different fiber volume fractions of 43mm macrobasalt fibers have been studied. The results show that the punching shear capacity and the ductility of the slabs were slightly improved with increasing the fiber content. Furthermore, the results also indicate that the outcome of the experimental method is valid when the rotation of the slabs is negligible.
