Keywords:Beam-column joint, Joint hoops, Strength ratios, Deformation

The strength and deformation of the beam-column joint should be maintained in earthquake resistant design of reinforced concrete moment resisting frame because joint should have sufficient stiffness and strength to resist the load coming from the adjacent beams and columns. The main objective of this study was to widen the current knowledge and understanding of the effect of joint hoops on deformation and strength of interior beam-column joints. The main test parameters were the amount of joint hoops and the column-to-beam strength ratio, and the effect of joint hoops was investigated on deformation and strength of interior beam-column joints subjected to reversed cyclic loading.
