Background
Due to frequent earthquakes and the fact that the modern safety standard pays more and more attention to the safety of the structure, the existing beam-column joint structure tends to adopt a self-resetting structure. The self-resetting structure system is mainly characterized in that a prestressing device is arranged in the structure, so that the structure is automatically restored to an initial position to reduce residual displacement. The swing structure system prevents weak layers from occurring through structural integrity swing, so that deformation among all layers of the structure tends to be consistent, and structural damage is distributed more uniformly. The conventional beam-column node is known to be damaged and deformed in the residual mode in every earthquake, and some elastic deformation is slow in recovery and is more likely to generate unrecoverable plastic deformation.
