Abstract

The invention discloses a beam-column joint of a double-hinge recoverable functional steel frame, which relates to the technical field of steel frame structures. The steel frame beam-column joint includes: a double hinged connection piece, the double hinged connection piece includes a first side plate and a second side plate, and the first side plate and the second side plate can rotate in opposite directions; Wherein, the first side plate can be fixedly connected with the cantilever short steel beam; the second side plate can be fixedly connected with the long steel beam; the connection between the first side plate and the cantilever short steel beam, and the Energy dissipation plates are arranged at the joints between the two side plates and the long steel beams. The invention discloses a double hinged recoverable functional steel frame beam-column joint, which improves the deformation and stress mechanism of the original single hinged joint, increases the tensile deformation of the energy dissipation plate on the one hand, and reduces the load burden of the double hinged connection structure on the other hand.

Description

technical field [0001] The invention relates to the technical field of steel frame structures, in particular to a beam-column joint of a double-hinge recoverable functional steel frame. Background technique [0002] In the 1994 Northridge Earthquake in the United States and the 1995 Hanshin Earthquake in Japan, researchers found that rigid joints connected by welds are prone to brittle fracture failure, which is not conducive to giving full play to the superior seismic performance of steel frame structures. Therefore, scholars at home and abroad have successively carried out many studies on improved beam-column joints, among which the more representative ones are semi-rigid connection joints, weakened or strengthened joints. The semi-rigid joint reduces the bending stiffness of the beam end, which is beneficial to the energy dissipation in the joint area. In addition, by weakening or strengthening the joint area, the plastic zone can be moved outward, and the weld connectio...
