Unilateral prestress all-assembling type self-resetting steel frame joint

Abstract

The invention discloses a unilateral prestress all-assembling type self-resetting steel frame joint which comprises an H-shaped steel column, an H-shaped steel beam, an energy consuming part and a connecting part. The connecting part comprises an end plate, groove-type connectors, prestress steel strands and an anchorage plate. The end plate is hinged to a flange plate of the H-shaped steel column; the end of a flange plate of the H-shaped steel beam is connected with the end plate through the energy consuming part; the groove-type connectors are symmetrically arranged on the two sides of a web plate of the H-shaped steel beam; and the two ends of the prestress steel strands are anchored on the anchorage plate and the groove bottoms of the groove-type connectors. The unilateral prestress all-assembling type self-resetting steel frame joint does not have to penetrate through a core and can not weaken a column body. The unilateral prestress all-assembling type self-resetting steel framejoint is fixed into the H-shaped steel beam, and avoids additional bending moments generated by the prestress steel strands to the steel column. All assembling is achieved, and joint parts are conveyed to a site after prefabricated in a factory to be directly assembled, so that labor cost is lowered, and the dangerousness of high-altitude operation is lowered.

Description

technical field [0001] The invention belongs to the technical field of earthquake prevention and disaster reduction of building structures, and relates to a self-resetting steel frame node, in particular to a unilateral prestressed fully assembled self-resetting steel frame energy-consuming connection node. Background technique [0002] The self-resetting structure focuses on damage control and reducing post-earthquake economic losses, and belongs to the frontier field of earthquake prevention and disaster reduction of building structures. It 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. It meets the needs of national economic development and the owner's requirements for the seismic performance of the structure. It can easily achieve the anti-seismic fortification goal of "not damaged by small earthquakes, repairable by moderate earthquakes...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the existing technology, the purpose of the present invention is to provide a unilateral prestressed fully assembled self-resetting steel frame node, which solves the problem of weakening the column caused by the core penetration of the existing self-resetting node, and the need for on-site high-altitude operations and tensioning. A series of technical and construction issues
