Abstract: This paper proposes a joint system that connects the thin-walled square reinforced concrete–filled steel tube (RCFST) column to RC beams at both sides of the joint. In order to delay the local buckling of square steel tubes ...

Abstract: This study proposes a through-beam composite joint system to connect square concrete-filled steel tubular (CFST) columns and concrete-filled U-shaped steel (CFUS) beams. In the joint system, channel-shaped holes in the ...
