Replaceable energy-dissipating column base joint for fabricated integral frame

Abstract

The invention belongs to the technical field of building engineering, and relates to a replaceable energy-dissipating column base joint for a fabricated integral frame. According to the technical scheme, the base parts of a rectangular pre-fabricated frame column are sunken inwards from the four faces so as to ensure that all corner longitudinal ribs of the rectangular pre-fabricated frame columnare continuous, and the rectangular pre-fabricated frame column with the section being weakened is connected with a cast-in-place foundation; the outer contours of replaceable energy-dissipating standard steel members are matched with the inward-sunken parts of the rectangular pre-fabricated frame column in shape; the four replaceable energy-dissipating standard steel members are embedded into theinward-sunken parts correspondingly, the upper portions of the replaceable energy-dissipating standard steel members and the rectangular pre-fabricated frame column are fixed, and the lower portionsof the replaceable energy-dissipating standard steel members and the cast-in-place foundation are fixed; four replaceable energy-dissipating composite steel plates are tightly attached to the outer sides of the replaceable energy-dissipating standard steel members to form a steel plate barrel; and the upper portions of the replaceable energy-dissipating composite steel plates and the rectangular pre-fabricated frame column are fixed, and the bottoms of the replaceable energy-dissipating composite steel plates and the cast-in-place foundation are fixed. According to the replaceable energy-dissipating column base joint for the fabricated integral frame, the problem of rapid repair of an earthquake damaged pre-fabricated frame column is solved, and the overall seismic performance of the fabricated frame structure is improved.

Description

technical field [0001] This patent belongs to the technical field of construction engineering, and specifically relates to a replaceable energy-consuming composite column structure system. Background technique [0002] In the existing prefabricated frame system, the flexural rigidity of the frame columns within the bottom reinforcement area varies greatly, which affects the development of the beam-column plastic hinge area, and then affects the overall seismic performance of the structure. [0003] The existing replaceable energy-dissipating composite column structure has poor energy-dissipating performance and cannot work well with the original concrete column, and energy-dissipating materials cannot fully play their roles. [0004] The construction technology of the existing replaceable energy-consuming assembly is relatively complicated. When the column foot has a large displacement angle, the energy-consuming part will be greatly deformed, which makes it difficult to dis...

Problems solved by technology

[0006] At present, most of the domestic and foreign research results on replaceable energy-dissipating nodes in earthquake damage are concentrated on the shear wall structure system and the steel frame structure system, and there are few research results on the assembled integral frame structure system.
