Performance of Corbels Containing SIFCON: Experimental Study

SIFCON can be considered as a special type of fiber reinforced concrete (FRC) where the fiber content is ranging from 4 to 20%, the method of its casting has a specified way in which the fiber is infiltrated by cement-based slurry. In this paper, the experimental work of testing SIFCON corbels subjected to vertical loads is presented. Six corbels which had fractional volume of the steel fibers 6%, 8% and 10% and two values of shear span/effective depth ratio (a/d) (0.35 and 0.7) were tested in addition to one specimen reinforced with steel bars and 6% steel fibers. It was found the ultimate strength and ductility increased by the increase of the content of steel fibers, the best performance of corbels was for specimen with steel bars and a/d equal to 0.35.
