Abstract
This research contains a study of the effect of connecting square steel pieces (10mm) thick with dimensions (20×20,25×25,30×30mm) 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
