EFFECT OF CONCRETE COMPRESSIVE STRENGTH ON PERFORMANCE OF FIBROUS REINFORCED CONCRETE CORBELS
Journal Title: Engineering and Technology Journal - Year 2017, Vol 2, Issue 11
Abstract
This paper presents an experimental investigation to study the behavior of fibrous high strength concrete corbels under the effect of static load. Totally six specimens with clear span to depth ratio equal to (0.7) were tested to failure. Three of the specimens provided with normal strength concrete with three different amounts of steel fibers (0%), (1%) and (2%) of total volume and three specimens provided with high strength concrete with same different ratios of steel fibers. The influence of concrete strength on the ultimate capacity, cracking capacity, load-deflection behavior, failure pattern and stiffness has been studied. Test results indicate that, the corbels with normal and high strength concrete were failed in diagonal shear mode. Also, the results showed that, the high strength concrete specimens generated higher ultimate capacity, cracking capacity, and stiffness than normal strength concrete.
