The invention discloses a self-resetting concrete-filled circular steel tube frame beam-column joint with energy dissipation parts on webs. The self-resetting concrete-filled circular steel tube framebeam-column joint comprises a concrete-filled circular steel tube column, an H-shaped steel beam, the energy dissipation parts, column connectors, grooved connectors, prestressed steel strands and ananchoring plate, wherein one end of each prestressed steel strand is anchored to the bottom of the corresponding grooved connector and the other end of each prestressed steel strand is anchored to the anchoring plate; and two ends of each energy dissipation part are connected to the corresponding web of an H-shaped short beam and the corresponding web of the H-shaped steel beam. Energy dissipation plates are arranged on the webs, so that the self-resetting concrete-filled circular steel tube frame beam-column joint has no influence on the construction of floors and is capable of being easilyreplaced after seismic damage and avoiding the situation that the energy dissipation plates are deformed resulting in cracking of the floors. Various processes such as welding of the column part and the grooved connectors of the self-resetting concrete-filled circular steel tube frame beam-column joint are completed in a factory, and then transported to a site for direct assembly after being prefabricated in the factory so as to realize prefabrication, reduce the labor cost and reduce the risk of overhead working.
Description
technical field [0001] The invention belongs to the technical field of earthquake prevention and disaster reduction of building structures, and in particular relates to a self-resetting circular steel pipe concrete frame beam-column node with webs and energy-dissipating parts. Background technique [0002] The self-resetting structure has the advantages of dissipating seismic energy and reducing seismic action, reducing or avoiding damage to the main structure and minimizing residual deformation of the structure. Afterwards, only the energy-consuming parts need to be replaced, and the structure can be quickly restored to normal working condition, which can significantly reduce the post-earthquake repair cost. It meets the needs of national economic development and the owner's requirements for the seismic performance of the structure. In recent years, the research on self-resetting structures has attracted extensive attention of researchers. [0003] Because the confinement...
