SEISMIC BEHAVIOR AND SHEAR STRENGTH OF FRAMED JOINT USING STEEL-FIBER REINFORCED CONCRETE

The experimental results are presented of five exterior and seven interior beam-column joints that use steel-fiber reinforced concrete (SFRC) under reversed cyclic loading. The study covered reinforcement ratio of beam bars, the volume ratio of the stirrups in the joint core, and the development length of the beam bar in the joint. It was found that SFRC increases joint shear strength, as well as better ductility and better energy-dissipation capaciities. These and other study results are discussed. It is suggested that SFRC in beam-column joints may be applied in seismic areas. The paper also presents design recommendations and a formula for joint shear strength.
