Bottom-hinged-supporting low-damage self-reset shear wall

Abstract

The invention relates to a bottom-hinged-supporting low-damage self-reset shear wall. The bottom-hinged-supporting low-damage self-resetting shear wall comprises a reinforced concrete wall plate, a self-reset wall bottom and a foundation beam; the reinforced concrete wall plate is connected with the upper end of the self-reset wall bottom, the foundation beam is connected with the lower end of theself-reset wall bottom, a connecting plate is arranged in the middle of the upper surface of the foundation beam and provided with a connecting beam hinged joint, and self-reset short support hingedjoints II are arranged on the two sides of the connecting beam hinged joint correspondingly; the self-reset wall bottom comprises a connecting beam and a self-reset short support; an anti-shear key isarranged on the upper surface of the connecting beam, a foundation beam hinged joint is arranged in the middle of the lower surface of the connecting beam, and self-reset short support hinged jointsI are arranged on the positions, corresponding to the two self-reset short support hinged joints II, of the two ends of the lower surface of the connecting beam; and the self-reset short support comprises an inner pipe, an outer pipe, a disc spring and baffles, the disc spring is arranged in the outer pipe, the baffles are arranged at the two ends of the disc spring, the inner pipe penetrates through an inner hole of the disc spring and the baffles at the two ends and are capped at the two ends of the inner pipe through a stop block, and self-reset short support hinged joints III are arrangedat the two ends of the self-reset short support.

Description

technical field [0001] The invention belongs to the technical field of building structures, and relates to a shear wall with a self-resetting function, in particular to an assembled-produced reinforced concrete shear wall with a resetting capability that includes concrete, steel bars, section steel and self-resetting supports. Background technique [0002] Earthquake is one of the major natural disasters faced by human society today. It has the characteristics of strong suddenness, great destructiveness, far-reaching social impact and can cause secondary disasters. It is easy to cause casualties, collapse of buildings, traffic paralysis, communication interruption and Lifeline engineering destroyed. The traditional seismic design concept takes life protection as the primary goal, and the ductile design of the structure is achieved by generating plastic deformation and irreversible damage. This method effectively reduces casualties and building collapses, but the severe damag...

Problems solved by technology

[0004] The invention solves the problem that when the traditional concrete shear wall is deformed, the foot of the wall is easily crushed, the bottom of the wall is easy to form a plastic hinge and the ductility is insufficient, the bearing capacity of the prestressed self-resetting concrete shear wall is...
