Abstract
An assembled self-recovery circular concrete-filled steel-tube composite joint includes a circular steel-tube column and H-shaped steel beams, where steel bars penetrate through the circular steel-tube column; the circular steel-tube column includes an upper steel-tube column section, a central inserted-connection column section and a lower steel-tube column section; the upper steel-tube column section is connected to the central inserted-connection column section through an upper sleeve connector, and the central inserted-connection column section is connected to the lower steel-tube column section through a lower sleeve connector; and the H-shaped steel beams are connected to the circular steel-tube column through the upper sleeve connector and the lower sleeve connector. According to the assembled self-recovery circular concrete-filled steel-tube composite joint, all members are machined in a factory and are connected on site through bolts.
