Abstract

This study explores the application of various fibres to augment the punching shear capability of flat slabs. The incorporation of hybrid fibres in concrete mixes necessitates careful evaluation of the distinct characteristics and advantages offered by each type of fibre in concrete. A total of eight mix elements, each measuring 150x150x150 mm in cube form and 150x300 mm in cylindrical form, were subjected to concentric loading conditions until fracture occurred. T We classified the mixtures into three categories to examine the impact of various types and quantities of fibres. The test results showed that slab elements with three types of hybrid fibres (mix 7) have a punching shear capacity that is 10% to 13.2% higher than slab elements with only two types of hybrid fibres. Conversely, the combinations of two different types of hybrid fibres resulted in a punching shear capacity that was 8% greater than that achieved with only one type of fibre. Additionally, there was a 15% reduction in deflection and a 12% increase in stiffness. The mix with three hybrid fibers had a 70% higher maximum punching strength and a 54% higher energy absorption rate than the control slab, which didn't have any fibers. Additionally, the same mix reduced the deflection by 52% compared to the control mix.
