Shear wall corner replaceable energy dissipation component and energy dissipation structure

Abstract

The invention provides a shear wall corner replaceable energy dissipation component, which comprises connecting sections and a main body section, wherein the connecting sections are arranged at the upper and lower ends, the main body section is arranged in the middle, the connecting sections are used for connecting a shear wall, the main body section comprises a steel pipe concrete section and a pre-tightening self filling section, the steel pipe concrete section comprises a pressure-resistant steel plate, steel pipes, concrete and an anti-bending inner core, the pressure-resistant steel plate is positioned at the upper part, the steel pipes are positioned on the periphery and are used as outer walls, the concrete and the anti-bending inner core are positioned at the inside, the pre-tightening self filling section comprises an inclined steel supporter, a plurality of pressure-resistant steel gaskets and a pre-tightening coil, when being pulled, the anti-bending inner core and the steel pipe concrete are disconnected, the steel pipe concrete cannot be damaged through pulling, and the pre-tightening self filling section can automatically fill gaps formed through pulling, so when being reversely stressed, the steel pipe concrete can immediately receive the force, the anti-bending inner core and the steel pipe concrete simultaneously bear the pressure, through the design, the damage of the shear wall can be concentrated on the replaceable component, and in addition, the shear wall corner replaceable energy dissipation component and the shear wall are detachably connected, so the anti-seismic function of the shear wall can be fast recovered through replacing the replaceable component after an earthquake.

Description

technical field [0001] The invention belongs to the technical field of buildings, and relates to an anti-shock and shock-absorbing technology, in particular to an anti-shock and shock-absorbing technology for a reinforced concrete shear wall of a high-rise building structure. Background technique [0002] Earthquakes will not only cause direct economic losses, but also cause indirect economic losses such as temporary stop or reduction of production, disturbance of the original balanced economic system, or reduction of external investment. Past earthquake damage experience shows that the indirect economic losses of earthquake disasters around the world Losses often go beyond direct economic losses. [0003] As one of the most widely used lateral force structures in high-rise structures, reinforced concrete shear walls play an important role in seismic fortification. In high-rise structures, the main function of reinforced concrete shear walls is to provide greater stiffness a...

Problems solved by technology

[0004] The compressive bearing capacity of general concrete wall pieces is about 3-5 times of the tensile bearing capacity, and the existing energy dissipators or tensile bearings all have the phenomenon that the stiffness or bearing capacity does not match the shear wall, for example: The stiffness of the hysteresis damper or the frictional energy dissipator is too small; the tensile and compressive bearing capacity of the metal type energy dissipator or the anti-buckling support is basically equal, which does not match the characteristic that the compressive resistance of the concrete shear wall is much greater than the tensile bearing capacity; the soft steel rubber The support is made of rubber, which will cause a significant decrease in the stiffness of the shear wall
