The invention discloses a self-resetting beam-column energy-dissipating node, which includes vertically arranged steel columns and horizontally arranged steel beams; C-type shock-absorbing energy-dissipating steel plate; the invention forms a pre-compression bending moment through the pre-compression of disc springs, ensures that the node structure has good self-resetting performance, and reduces the rotation radius and stiffness requirements of the steel beam through the square support member, and Combined with C-type shock-absorbing energy-dissipating steel plates, it dissipates a large amount of energy input into the structure by the earthquake, effectively avoiding the formation of plastic hinges similar to traditional steel frame beam-column joints, and achieving no or slight damage to beam-column joints under large earthquakes , After the earthquake, the nodes can be put into use without repair or minor repair.
Description
technical field [0001] The invention relates to energy dissipation and shock absorption technology in the field of steel structure buildings, and more specifically relates to a self-resetting beam-column energy dissipation 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 long, which will in...
