Abstract

The invention discloses a double-hinge recoverable function steel frame beam-column joint, and relates to the technical field of steel frame structures. The double-hinge recoverable function steel frame beam-column joint comprises a double-hinge connecting piece, the double-hinge connecting piece comprises a first side plate and a second side plate, and the first side plate and the second side plate can rotate in the opposite directions; the first side plate can be fixedly connected with a cantilever short steel beam; and the second side plate can be fixedly connected with a long steel beam. According to the double-hinge recoverable function steel frame beam-column joint, the deformation and stress mechanism of an original single-hinged joint is improved, on the one hand, the tensile deformation of an energy consumption plate is increased, and on the other hand, the load burden of a double-hinged connection structure is relieved.

Description

Technical field [0001] The present invention relates to the technical field of steel frame structures, and more particularly to a double hinge recoverable function steel frame beam column node. Background technique [0002] In the 1994 Northern Earthquake and in the 1995 Japanese Hanshi earthquake, the researchers found that the brittle fracture is prone to brittle fracture by the rigid node connected to the weld, which is not conducive to the excellent earthquake resistance of the steel frame structure. Therefore, domestic and foreign scholars have launched many research on the improvement of beam column nodes, which are relatively representative of semi-rigid connecting nodes, weaken or enhanced nodes. The semi-rigid node reduces the beam of the beam, which is conducive to the energy consumption of the node area. In addition, by weakening or reinforcing the node area, the plastic zone can be achieved, and the force of the weld connection area is too large to enter the plastic f...
