Abstract
This study is conducted to investigate effect of footing thickness(100,120 140 mm) and steel fiber ratio (0,1,1.5 %) on punching shear failure of self-compacting concrete(SCC)pad footing. The specimens were supported on a bed of steel(car)springs and loaded by vertical centric force. The results showed that the first crack load and ultimate load, ductility and strength improve as the thickness increase and failed by punching shear failure. After adding steel fiber with different ratio the result showed that the first crack load , ultimate load , strength and ductility increase with increasing of steel fiber ratio and failed by flexural punching failure, Also, It is noticed that failure of all specimens without steel fibers was sudden and brittle as compared to those with steel fibers in which failure was gradually.
