This paper proposes new joints between column bases of steel superstructure and Steel Concrete (SC) grade beams that make moment transfer possible with large stiffness. Three types of joints are devised: (a) reinforcing the H-shaped steel in the SC grade beam by stiffeners, (b) reinforcing the upper flange with T-shaped steel, and (c) connecting the base plate and the bottom flange with screw bars. Full-scale tests were conducted using simply supported SC beams with cantilever columns. The stiffnesses of the proposed column bases were 3 to 4 times that of the conventional exposed-type column base.
