Assembled self-resetting energy dissipation shear wall

Abstract

The invention discloses an assembled self-resetting energy dissipation shear wall which comprises a foundation, a plurality of concrete filled steel tubular columns, dampers, high strength anchor rodsand nuts. A steel plate is pre-buried in the foundation; the concrete filled steel tubular columns are arranged in a spaced manner on the top surface of the foundation, and each concrete filled steeltubular column is composed of multiple segments; the concrete filled steel tubular columns are provided with radial protruding cantilever slabs on the side wall of the bottom close to the top surfaceof the foundation; the dampers are fixed between adjacent two concrete filled steel tubular columns; the top end of the high strength anchor rods penetrate the cantilever slabs and are provided withdisc spring groups in a sleeving manner, and the bottom ends of the high strength anchor rods are inserted into the foundation and penetrate the pre-buried steel plate; and the nuts are separately fastened to two ends of the high strength anchor rods. The assembled self-resetting energy dissipation shear wall is simple in structure, flexible in design and convenient to construct. The repairing orreinforcing cost of the structure after an earthquake can be reduced effectively as a result of the self-resetting ability of the assembled self-resetting energy dissipation shear wall, so that the recoverable capability of the structure after earthquake in use function is improved integrally.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption of building structures, in particular to an assembled self-resetting energy dissipation shear wall. Background technique [0002] At present, the traditional anti-seismic thinking takes protecting life as the primary goal, and prevents structures from collapsing under strong earthquakes through ductile design. However, this ductile design comes at the expense of allowing plastic deformation of the main stressed members of the structure. On the other hand, the structure may be subjected to earthquakes stronger than the fortification intensity during use, which will also cause damage and residual deformation of the structure. In fact, earthquake disasters in recent years have shown that the number of building collapses and casualties in earthquakes has been effectively controlled, but the economic losses and social impacts caused by earthquakes are still huge, and a ...

Problems solved by technology

Although the current partial prefabricated shear wall structures can realize the reliability and convenience of connection through various construction methods, most of them have poor self-resetting and energy dissipation performance, and it is difficult to effectively ensure the safety of the structure under strong earthquakes.
