Assembly type steel structure energy consumption type beam column joint and assembling method thereof

Abstract

The invention relates to an assembly type steel structure energy consumption type beam column joint and an assembling method thereof. The assembly type steel structure energy consumption type beam column joint comprises a steel frame column, an upper bracket and a lower bracket are vertically welded to the side face of the steel frame column, one end of the upper bracket is connected with one endof a shear plate through high-strength bolts, the other end of the shear plate is connected with a web of a steel frame beam through high-strength bolts, and the upper bracket and an upper flange of the steel frame beam are connected with a flange clamping plate through high-strength bolts; a lower flange of the steel frame beam is connected with a damper and the lower bracket through high-strength bolts. The assembly type steel structure energy consumption type beam column joint and the assembling method thereof have the advantage of improving the seismic energy consumption property of the structure.

Description

technical field [0001] The invention belongs to the technical field of building steel structures, and in particular relates to an energy-dissipating beam-column node of an assembled steel structure and an assembly method thereof. Background technique [0002] In recent years, steel structures have been widely used in various building structures because of their advantages such as high strength, good seismic performance, and short construction period. In multi-story steel structure buildings, the weakest and most dangerous parts are usually the beam-column joints. When a structure encounters an earthquake, especially a destructive earthquake with high intensity, the beam-column joints in the structure are often unable to absorb and consume seismic energy due to their high stiffness, resulting in excessive buckling deformation at the joints, even Brittle fracture occurs, which seriously threatens people's life and property safety. [0003] At present, the commonly used metho...

AI Technical Summary

Problems solved by technology

However, due to the plastic damage area of ​​the main structure in this way, it will bring great difficulties to the repair after the earthquake, and at the same time, the repair of this structure after the earthquake will bring huge economic losses

The other is to dissipate the seismic energy by setting additional energy-dissipating and shock-absorbing devices. The common ones are metal dampers, viscous dampers, and tuned mass dampers. Although this method can overcome the shortcomings of the first method, the This method will take up a lot of space
