Connection details for RC column-steel beam (RCS) moment frames were developed to improve the productivity and constructability. To strengthen the beam-column joint, transverse beams, studs, and U-cross ties were used. Four 2/3 scale interior RCS connections were tested under cyclic lateral loading. The specimens generally exhibited good deformation capacity exceeding 4.0% story drift ratio. Ultimately, the specimens failed due to bearing failure of concrete and shear failure of the joint panel.
