Pullout Strength of Headed Deformed Reinforcement Embedded in Fibrous Concrete
Abstract
This research contains a study of the effect of connecting square steel pieces (10mm) thick with dimensions (2020,2525,3030mm) by welding with the ends of reinforced steel bars with diameters (10,12,16mm) embedded in fibrous concrete with a percentage volume of steel fibers (0.0,0.4,0.8,1.2%) over the development length required to reach steel reinforcement to yield strength ( )in case of straight reinforcement steel bars with the same diameters without steel headed.Keywords: fibrous concrete; anchors; headed reinforcement
