Description

Self-resetting energy dissipation supporting structure for steel keel type shear wall

Technical Field

The utility model belongs to the technical field of civil engineering, and relates to a self-resetting energy-dissipation supporting structure for a steel keel type shear wall.

Background

The key to earthquake resistance and disaster reduction lies in enhancing the earthquake resistance of buildings. Shear walls are the core seismic components of building structures. The cold-formed thin-wall steel keel type composite wall body is formed from cold-formed thin-wall steel keel frame and various panels. The keel frame is composed of C-shaped (curled edge groove-shaped cross section) steel upright posts and U-shaped (common groove-shaped cross section) guide beams, various covering panels are used as a building enclosure and simultaneously provide effective lateral support for the steel keel, and simultaneously restrain the torsion of the steel keel, so that the stable bearing capacity of the wall body is obviously improved, the steel keel has good anti-seismic performance and horizontal load resistance, but the ductility of the wall body is not enough, and vertical seams are arranged in the shear wall.

A horizontal seam is arranged in the shear wall structure, so that the deformation of the shear wall is concentrated at the horizontal seam; the horizontal seam is provided with an energy dissipation and shock absorption device which yields when being pulled and is not pressed when being pressed, and the energy dissipation performance similar to that of a small buckling restrained brace is presented, so that the energy dissipation capacity of the shear wall is enhanced; the pin is used for connecting the steel plate to protect the damage performance of the leg part of the lateral shear wall of the horizontal seam; the packing layer is used for preventing the energy dissipation and shock absorption device from being corroded while not providing rigidity. The shear wall structure is suitable for the shear wall structure with the seismic fortification intensity of 6 degrees or more. The shear wall has the advantages of clear design of anti-seismic concept, simple structure, convenient construction, low cost of used materials, good hysteretic energy dissipation capability and less damage than the structure of the traditional shear wall under the same large deformation condition. But the scheme still does not change the failure mode of the low shear wall in the using process, still belongs to brittle failure and is difficult to automatically reset and effectively resist earthquake.
