The invention provides a plasticity-controllable assembly type RCS structure beam-column joint. An upper prefabricated reinforced concrete column and a lower prefabricated reinforced concrete column are connected with each other on the opposite sides through threaded sleeves; a square steel tube is sleeved outside the steel bars which are connected with each other through the threaded sleeves, andconcrete is filled in the square steel tube; a first perforated connecting plate is welded to the side wall of the square steel tube, a double-lug hinge support is fixedly connected with the side wall of the square steel tube, and a lug plate of the double-lug hinge support is exposed to the outer side of the first perforated connecting plate; a second perforated connecting plate is welded to theside face of a prefabricated steel beam, and a single-lug hinged support is fixedly connected with the second perforated connecting plate; the lug plate of the double-lug hinge support is connected with a lug plate of the single-lug hinge support through a pin shaft; two ends of a perforated channel steel plate are connected with the first perforated connecting plate and the second perforated connecting plate through bolts; and hinged buckling-restrained brace components are connected between the upper prefabricated reinforced concrete column and the side wall of the prefabricated steel beamand connected between the lower prefabricated reinforced concrete column and the side wall of the prefabricated steel beam.
Description
technical field [0001] The invention relates to the field of civil engineering structures, in particular to a beam-column joint of a plastically controllable assembled RCS structure. Background technique [0002] The RCS structure is composed of reinforced concrete columns and steel beams, which is a new type of composite structure. The RCS composite structure organically combines the advantages of concrete and steel in terms of compression resistance, bending resistance, and ductility. Compared with steel structures, reinforced concrete columns can effectively increase the lateral stiffness of the structure and have better fire resistance; compared with reinforced concrete structures, steel beams can be constructed quickly and have lighter weight, which can also increase the vertical use space. Therefore, the RCS structure has received extensive attention and research in recent years. [0003] However, since the beam-column joints of the RCS composite structure are compos...
