Problems solved by technology

However, this kind of joint form does not show proper ductility in earthquakes, but brittle fracture occurs prematurely, and the crack usually originates from the weld of beam-column joints

Abstract

The invention discloses a novel special-shaped steel column frame-steel plate shear wall easy to restore after an earthquake. According to the novel special-shaped steel column frame-steel plate shear wall easy to restore after the earthquake, a double-groove steel beam is connected with a special-shaped column through a beam-end sealing plate, so that a welding-line-free full-bolt connecting form is formed; a prestress steel cable is applied to a welding-line-free full-bolt joint, so that a prestress self-reset joint is formed; a self-reset column base and a prestress column base are used for optimizing the axial mechanical performance and the horizontal mechanical performance of the bottom of the column through a reinforcing plate, a bend-preventing steel plate is mainly used for dissipating energy of the earthquake, and a shear plate is used for preventing local deformation, caused by excessive shearing force, of the bottom of the column; the key component of the prestress column base is a prestress pull rod, the pull rod is used for providing precompression for the column so that the column can be tightly connected with the beam, as a result, approximate rigid connection can be achieved when the prestress column base bears small bending moment, and the self-reset capacity of the prestress column base after the earthquake is achieved; better shock resistance of the structure is achieved due to the steel plate shear wall.

Description

technical field [0001] The invention relates to an easily repairable steel special-shaped column frame-steel plate shear wall, which belongs to the technical field of earthquake resistance and disaster reduction, and in particular to a novel post-earthquake easy-to-repair steel special-shaped column frame-steel plate shear wall. Background technique [0002] The collapse of buildings in earthquakes is the main reason that threatens people's lives and causes property losses. The earthquakes in Wenchuan and Ya’an showed that the seismic performance of concrete structures is not good. At present, my country’s steel structures are developing rapidly, especially the prestressed steel structure technology is at the international advanced level. The world record for the largest structural span leads the development of prestressed steel structures. Making full use of the advantages of prestressing technology and applying it to the steel frame joints will improve the seismic performa...
