Abstract

The growth of Development techniques for high strength materials and precast structures leads to increase the interesting on these technics. This study will focus on the corbels which made from high strength materials (Reactive Powder Concrete materials) which including the testing of (15 samples) and their cost, twelve of them were testing under a vertical monotonic load, while the other sample putted under the effect of repeated load. As well as, the samples divided to various groups according to many variable parameters which are (ratio of steel fiber, (a/d) ratio, existing the secondary stirrups steel, type of loading). Thus, these parameters effected on the ultimate shear strength, first crack loading, ultimate deflection, load-deflection curves, ductility and stiffness.
