REINFORCED STEEL FIBER CONCRETE CORBELS WITH VARIOUS SHEAR SPAN-TO-DEPTH RATIOS

Vertical loading tests were carried out on 150 x 150 x 200 mm (6 x 6 x 8 in) concrete corbels reinforced with main bars only or with main bars and steel fibers. The fibers were used as secondary (shear) reinforcement, and both the volume of main bars and shear span-to-depth ratio were varied. The tests indicated that corbels reinforced only with main bars failed suddenly and catastrophically, and the mode of failure was generally diagonal spliltting or constrained shear. However, corbels reinforced with main bars and steel fibers failed in a more gradual and ductile manner, and the mode of failure was generally inclined shear or flexure. Corbels reinforced with a low volume of main bars and tested at a relatively large shear span-to-depth ratio exhibited an almost elastic-plastic behavior.
