Behavior of Reinforced Concrete Corbels Strengthened with CFRP Strips Subjected to Monotonic and Repeated Loading

Tikrit Journal of Engineering Sciences
Concrete corbels are short cantilevers subjected to monotonic and repeated loads. Repeated loads generally negatively affect the concrete structural members' strength as they decrease the resistance to external loads.

Effect of Concrete Compressive Strength on Performance of Fibrous Reinforced Concrete Corbels

Engineering and Technology Journal, 2017
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%
