Description
Technical field
The present invention relates to a kind of anti-buckling not damaged functions of support energy consumption can restore shear wall, belongs to civil engineering work knot
Structure technical field.
Background technique
Shear wall is the key member of Multistory-tall building antidetonation, influences integrally-built anti-seismic performance, domestic and international researcher
Various shearing wall members are studied, have obtained many important research achievements, but existing shear wall is under geological process
Damage can occur even to destroy, be difficult to repair.Therefore, it is the hot issue studied at present that function, which can restore structure,.
General utility functions can restore shear wall structure mainly by disconnecting shear wall structure bottom, by prestressed cable and attached
It adds and sets energy consumer to increase energy consumption；Or realized by the way that replaceable coupling beam is arranged, i.e., it is consumed energy by coupling beam and after shake
Realize that function can be restored by replacement coupling beam；But these methods without considering shear wall folding corner region under geological process very well
Damage and destruction, cause shear wall damage after structure function be difficult to the function for restoring, quickly repairing after damaging with structural earthquake
It can require, current many structures apply prestressing force in the structure, enhance its Self-resetting energy by introducing prestressing force self-reset technique
Power.Therefore the good undamaged function of research anti-seismic performance can restore shear wall to quickly repairing structure skill after promoting seismic Damage
Art has great importance.
Summary of the invention
The invention proposes a kind of anti-buckling not damaged functions of support energy consumption can restore shear wall, in shear wall corner rapid wear
Wound destroys position setting vacancy position and forms special-shaped shear wall, and installs steel plate energy dissipation brace at vacancy position, then by anti-
Buckling-restrained component constraint support prevents buckling, runs through special-shaped shear wall finally by prestressed cable and basis links together,
Shear wall can be restored by forming a kind of not damaged function of anti-buckling support energy consumption.Its light plate energy dissipation brace is consumed by anti-buckling enhancing
Can, mechanical behavior is clear, Yi Genghuan, and special-shaped shear wall main structure is not damaged, so that reaching not damaged function can be extensive
Multiple effect.The present invention is suitable for civil engineering structure, and research object is shear wall structure.Simple structure of the present invention, stress machine
It makes clear, Yi Genghuan and there is good anti-seismic performance.
Technical scheme is as follows:
A kind of not damaged function of anti-buckling support energy consumption can restore shear wall, special-shaped shear wall, steel including corner vacancy
Plate energy dissipation brace, anti-buckling confining part, high-strength bolt, prestressed cable, it is characterised in that: be base below special-shaped shear wall
There is vacancy position in corner to be fixedly connected with steel plate energy dissipation brace with basis by high-strength bolt for plinth, special-shaped shear wall lower end, i.e.,
Steel plate energy dissipation brace is located at vacancy position, and steel plate energy dissipation brace upper end is fixedly connected with the upper surface at vacancy position, steel plate energy consumption
Support lower end is fixedly connected with basis, and anti-buckling confining part setting carries out constraint support around steel plate energy dissipation brace；And lead to
Cross that prestressed cable runs through special-shaped shear wall and basis links together, forming a kind of not damaged function of anti-buckling support energy consumption can be extensive
Multiple shear wall.
Corner vacancy position is multiple, formation symmetrical structure.
Steel plate energy dissipation brace may include different in width, different-thickness and different cross section shape (linear type, cross).
Anti-buckling confining part can wrap up steel plate energy dissipation brace for armored concrete or constrain steel plate energy consumption using fashioned iron
Support.
Corner vacancy abnormal shape shear wall is reinforced concrete wall or steel plate combination wall.
Prestressed cable is single hole prestressing force arrangement or porous arrangement on special-shaped shear wall cross section.
Steel plate energy dissipation brace is directly consumed energy by tension and compression deformation, and energy dissipation capacity is strong；Steel plate energy dissipation brace is arranged in shear wall
Corner is easy to damage and destroys position, and band replaces Partial Shear wall, and shear wall itself keeps elasticity, does not occur to damage and destroy, steel
After plate energy dissipation brace destroys, the fast quick-recovery of function can be realized by the steel plate energy dissipation brace more renewed；According further to shear wall
Size and energy consumption demand can be set the steel plate support of different in width and different-thickness and adjust the prestressing force of prestressed cable
Level realizes different demands.
Compared with general shear wall, the invention has the advantages that
(1) this special-shaped shear wall, steel plate energy-consumption supporting member concentrated setting is in shear wall easy damaged and destroyed area, protection
Shear wall does not damage, and mechanical behavior is clear.
(2) directly by the tension and compression of steel plate energy dissipation brace consume energy, energy dissipation capacity is stronger, and can by adjust support width and
Thickness and cross sectional shape realize different energy consumption demands.
(3) by joint prestressing force, have the function of Self-resetting, Yi Genghuan, can quick-recovery fastly advantage.
(4) material therefor is low in cost, simple structure.
