الملخص الإنجليزي

This research is conducted to study the effect of increasing footing thickness, flexural reinforcement ratios, and using funnel-shaped punching shear preventers (FSPSP) on the punching shear failure of self-compacting concrete (SCC) pad footing.

Four reinforced concrete footing specimens were supported on a bed of steel (car)springs and loaded by vertical load till failure.

The results showed that the ultimate load, the ductility, and the punching shear strength were improved by increasing footing thickness and using the FSPSP.

The results also showed that the ultimate load increased with increasing of the flexural reinforcement ratio while the ductility and the deflection are decreased.

It was found that the best results were obtained by using FSPSP, about 66% increasing in ultimate load.
