The invention discloses a resilient self-resetting beam column energy dissipation joint. The resilient self-resetting beam column energy dissipation joint comprises a vertically-arranged steel columnand a horizontally-arranged steel beam, and further comprises a flush type end plate, reinforcing plates, angle steel, a square supporting component, a high-strength pull rod and belleville springs. According to the resilient self-resetting beam column energy dissipation joint, the pre-pressing bending moment is formed through the pre-pressure of the belleville springs, it is guaranteed that a joint structure has better self-resetting performance, the rotating radius of the steel beam is reduced through a square supporting component, a large amount of energy input into the structure by an earthquake is dissipated by combining the angle steel, forming of plastic hinges similar to a traditional steel frame beam-column joint is effectively avoided, the beam-column joint is free of damage or slight damage under the action of the large earthquake, and the joint can be put into use without being repaired after the earthquake.
Description
technical field [0001] The invention relates to the energy dissipation and shock absorption technology in the field of steel structure buildings, and more specifically relates to a recoverable self-resetting beam-column energy-dissipating node. Background technique [0002] At present, seismic structures with recoverable functions have become a research hotspot in the field of earthquake engineering in recent years. Although the parameters and methods of seismic design codes in various countries are different, for rare earthquakes, the current construction field mainly avoids casualties caused by the collapse of buildings under high-intensity earthquakes by increasing the ductility design of structures. At the current stage, this kind of anti-collapse design idea is reasonable and feasible, but this kind of design will lead to functional damage and residual deformation of the building structure, and it is difficult to repair after the earthquake or the repair time is too lon...
