Cross bracing type reinforced concrete energy consuming device

Abstract

The invention relates to a cross bracing type reinforced concrete energy consuming device, which belongs to the field of resistance and absorption of earthquake for construction structures, and overcomes the defects that the framework structure of reinforced concrete is small in lateral rigidity and easy to laterally sway under the action of the earthquake, and a traditional energy consuming device has the defects of high construction cost and large construction difficulty. The energy consuming device comprises a first and a second main bracings as well as a first and a second assistant bracings in a rectangular area ABCD, wherein the first main bracing is arranged on the diagonal AC of the rectangle ABCD; the second main bracing is arranged on the diagonal BD of the rectangle ABCD; or the first main bracing is arranged in the position deviating from a first vertex and a third vertex in a distance of 1 to 1.5 times the height of a framework beam, and is crossed with the upper edge and the lower edge of the rectangle ABCD; the second main bracing is arranged in the position deviating from a second vertex and a fourth vertex in a distance of 1 to 1.5 times the height of the framework beam, and is crossed with the upper edge and the lower edge of the rectangle ABCD; the assistant bracings are arranged on connecting lines of bisection points of four edges of the rectangle ABCD; the first and the second main bracings as well as the first and the second assistant bracings form a hollow grid; and when used as a filling wall, the hollow grid is filled with energy absorbing materials.

Description

technical field [0001] The invention relates to a reinforced concrete energy dissipation device used as the first anti-seismic defense line of a building structure, and belongs to the technical field of anti-seismic and shock absorption of building structures. Background technique [0002] Earthquakes will bring heavy casualties and huge economic losses to human beings. Earthquake disasters are mostly caused by house collapses. Therefore, improving the seismic performance of housing structures, fortifying new projects against earthquakes, and strengthening existing projects can greatly reduce earthquake disasters. . The anti-seismic capability of a structure depends on the energy dissipation capacity of each part of the structure. In the anti-seismic system, each part that consumes the input energy of the earthquake is called the anti-seismic defense line. A good anti-seismic structure system should set up as many lines of defense as possible. When a part of the structure i...
