Abstract

The testing program consisted of ten beam column joints with half of these joints containing 1. 5 percent by volume of concrete of steel hooked end fibers. The beam column joints were constructed with less hoops than a conventional seismic joint would have, according to design specifications of the American Concrete Institute code (ACI 318-77). From the analysis of the results, it can safely be concluded that the hooked end steel fibers in the joint region provided: 1) better bond; 2) better confinement of the concrete; 3) a stiffer member; 4) higher moment capacity; 5) higher shear strength; 6) more ductility; and 7) significant improvement in the energy dissipation capacity than did the plain concrete joint.
