Abstract

The invention relates to an anti-buckling energy consumption supporting non-damage shear wall with a restorable function, and belongs to the field of building structure engineering. The restorable shear wall with buckling resistance bracing energy dissipation and non-damage function includes a corner vacant special-shaped shear wall body, a steel plate energy dissipation support, a buckling resistance restraint member, high-strength bolts and a prestressed cable; a vacant part is arranged at the corner of the special-shaped shear wall body, the steel plate energy dissipation support is arranged on the vacant part with the high-strength bolts, and the width, the thickness, the cross-section shape and the prestress level are adjusted, different energy dissipation demands can be met; post-earthquake replacement of an energy dissipation member can realized by arranging the buckling resistance support separately to protect the wall body from being damaged, non-damage and the restorable function of the shear wall body can be achieved, and the shear wall is applicable to the design and application of a shear wall member in building shear wall structures. According to the anti-buckling energy consumption supporting non-damage shear wall with the restorable function, the force mechanism is clear, the shear wall has no damage and no residual deformation, the anti-seismic performance is excellent, and the anti-buckling energy consumption supporting non-damage shear wall with the restorable function has the advantages of being simple in structure and fast in function recovery.

Description

technical field [0001] The invention relates to a recoverable shear wall with an anti-buckling support that consumes energy and has no damage function, and belongs to the technical field of civil engineering building structures. Background technique [0002] Shear walls are the key components of multi-story structures aseismic, which affect the aseismic performance of the overall structure. Researchers at home and abroad have studied various shear wall components and obtained many important research results. Damage or even destruction will occur under the action, which is difficult to repair. Therefore, functionally recoverable structures are a hot topic of current research.

Problems solved by technology

[0003] The general function of the recoverable shear wall structure is mainly achieved by disconnecting the bottom of the shear wall structure, increasing energy consumption through prestressed cables and additional energy dissipation devices; or by setting replaceable connecting beams, that is, energy dissipation through connecting beams And after the earthquake, the function can be restored by replacing the coupling beams; but these methods do not take into account the damage and destruction of the corner area of ​​the shear wall under the earthquake, which makes it difficult to restore the structural function after the shear wall is damaged. Functional requirements for rapid repair after damage. At present, many structures introduce prestressed self-resetting technology to apply prestress to the structure to enhance its self-resetting ability.
