A double-steel tube concrete beam-column joint with internal FRP bar connectors is provided. The double-steel tube concrete beam-column joint includes double-steel tube columns, I-beams, a joint connector, an internal support member and external ring plates. Each double-steel tube column includes an internal steel tube and an external steel tube. The joint connector includes an internal connecting tube and an external connecting sleeve which are both circular steel tubes. The internal support member is a columnar structure and has two ends regularly formed with bolt holes in a circumferential direction. Each external ring plate comprises a horizontal portion and an annular portion perpendicular to the horizontal portion. Upper and lower double-steel tube columns are connected through the joint connector and the internal support member, the two ends of the internal support member are inserted into an upper internal steel tube and a lower internal steel tube, respectively.

A cylindrical sleeve-type steel-wood composite joint includes fiberglass reinforced panel (FRP) cylindrical wood columns, X-shaped wood beams, a key connecting component, arc connecting pieces and splicing outer ring plates. The key connecting component consists of upper and lower cylindrical steel sleeve plates, a connecting sleeve, a cylindrical solid wood and filling wood blocks. The FRP cylindrical wood columns are connected to the key connecting component and are inserted into the key connecting component through the cylindrical steel sleeve plates and penetrative steel bars. The X-shaped wood beams are connected to the key connecting component through the arc connecting pieces, and the splicing outer ring plates are fixed with bolts to realize combination and connection. By adoption of the design of the connecting sleeve, the joint has a high bearing capacity, vertical force transfer is guaranteed, operation is easy, and assembly is fast.
