A self-resetting circular steel pipe concrete frame beam-column joint with energy-dissipating parts on the web

Abstract

The invention discloses a self-resetting circular steel pipe concrete frame beam-column node with energy-dissipating parts on the web, including circular steel pipe concrete columns, H-shaped steel beams, energy-dissipating parts, column connectors, groove-type connectors, prestressed Steel strands and anchor plates; one end of the prestressed steel strands is anchored at the bottom of the channel connector, and the other end is anchored at the anchor plate; both ends of the energy-dissipating parts are connected to the web of the H-shaped short beam and the H-shaped steel web of the beam. In the present invention, the energy-dissipating plate is arranged on the web, which has no influence on the construction of the floor slab, and is easy to replace after earthquake damage, and does not cause the deformation of the energy-dissipating plate to cause the floor to crack. The column part and the groove-shaped connector of the present invention Various processes such as welding are completed in the factory, and the factory is prefabricated and then shipped to the site for diameter assembly, which realizes assembly, reduces labor costs, and reduces the danger of working at heights.

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...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a self-resetting circular steel tube concrete frame beam-column joint with energy-dissipating parts in the web, so as to adapt to the circular steel tube concrete frame widely used in building structures and solve the existing problems. The beam-column joints of the circular steel pipe concrete frame do not have the self-resetting function, the earthquake damage is difficult to repair, the on-site welding workload is large, the internal partition affects the quality of concrete pouring, the energy-consuming parts are not easy to replace, and the deformation of the energy-consuming parts damages the floor.
