Above-mentioned high strengthening tendons material 22 is steel strand wires or fiber-reinforced composite material rib；Above-mentioned has dual automatic recovery ability
Energy-consuming shear wall in, the concrete shear wall of left lower is positioned as A point, and the anchor point of the anchor slab of left upper portion is B, right
The anchor point of the anchor slab of upper lateral part is C, and the concrete shear wall of lower right side is positioned as D point, annular cross section V-arrangement damper cylinder
The lower end fixed point of cylinder (6) is E.
In order to reduce the flexible deformation of wirerope 11, and the relative displacement between shear wall BE (or CE) is converted as far as possible
For the relative displacement between annular cross section V-arrangement damper cylinder barrel 6 and piston rod 5, the wirerope 11 need to apply prestressing force.
Working principle of the utility model is:
Under Horizontal Seismic Load, shear wall structure can generate relative floor displacement, and shear wall body top is left and right
Relative to the point E of lower part reciprocal horizontal relative displacement occurs for terminal B, C, and the distance of BE two o'clock can be elongated or shorten.As BE two
When the distance of point is elongated (Distance Shortened of CE two o'clock at this time).Since damper cylinder barrel 6 is fixed on E point, wire rope connection point B
(or point C) and piston rod end, and wirerope is applied with prestressing force in advance, therefore, wirerope 11 shear wall BE (or CE) it
Between relative displacement be converted to the relative displacement between damper cylinder barrel 6 and piston rod 5.In damper left upper portion chamber 8
Volume-diminished, damping energy dissipation material flow into damper right upper portion chamber through fan annulus 9 and damp channel 4, damper
The piston and piston rod on right side are then close to E point under fluid pressure effect.When the distance of CE two o'clock is elongated, damper is right
Volume-diminished in upper lateral part chamber 8, damping energy dissipation material flow on the left of damper through fan annulus 9 and damp channel 4
In portion's chamber.Therefore, in earthquake, damping energy dissipation material flows back and forth in damp channel, will generate damping force and energy dissipating
Cushioning effect to effectively consume the seismic energy of incoming building structure, and reduces power of the structure under seismic loading
Response, improves the anti-seismic performance of building structure.
Since the high strengthening tendons material 22 and tie point B (or point of 21 arranged on left and right sides of reinforced concrete shear wall wall is arranged in
C) and the steel strand wires 12 of round cylinder cover plate 10 have very high tensile strength, and structure is constantly in elastic work under severe earthquake action
Make state.Therefore, when structure has residual deformation after macroseism, due to the presence of residual deformation, the distance between AB (or CD), with
It the distance between BE (or CE) and being elongated, high strengthening tendons material 22 and steel strand wires 12 generate elastic restoring force because being elongated, due to
The presence of dual restoring force, reinforced concrete shear wall wall are pulled back to original position quickly, residual deformation very little, thus
Make structure have it is dual can recovery capability.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model.
