Abstract
From exploratory research of reinforced fibrous concrete, it has been shown that fibrous concrete is potentially superior and less costly than the conventional reinforced concrete.
The testing program consisted of ten beam-column joints with half of these joints containing 1-1/2 percent 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). In studying the behavior of these beam-column joints, two loading cases were examined:
(1) critical regions whose inelastic behavior was controlled by bending, and
(2) critical regions whose inelastic behavior was controlled by high shear existing in the region rather than bending.
From the analysis of the results, it can safely be concluded that the hooked ended 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.
