Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the invention, fall within the scope of protection of the invention.
As shown in fig. 1-4, the invention provides an energy consumption shear wall with double self-recovery capability, which comprises a reinforced concrete shear wall body 21, wherein a common vertical distribution steel bar 23 and a common horizontal distribution steel bar 24 are arranged in the reinforced concrete shear wall body 21, the left side and the right side of the reinforced concrete shear wall body 21 are respectively provided with a vertical high-strength steel bar 22, an annular cross section V-shaped damper cylinder 6 is arranged between a front row of distribution steel bar meshes and a rear row of distribution steel bar meshes which are formed by the common vertical distribution steel bar 23 and the common horizontal distribution steel bar 24, the annular cross section V-shaped damper cylinder 6 and the reinforced concrete shear wall body 21 are poured together, the annular cross section V-shaped damper cylinder 6 is formed by an inner cylinder body and an outer cylinder body, an annular cross section V-shaped damping channel 4 is formed between the inner cylinder body and the outer cylinder body, the left end and the right end of the inner cylinder body are respectively provided with a piston rod 5, the lower end of the piston rod 5 is provided with a cylindrical piston 3, the lower end of the piston rod 5 on the left side of the inner cylinder body is provided with a cylindrical piston 3, and the lower end of the piston rod 5 on the right side of the inner cylinder body is filled with a sealing fluid damping material 1; the two ends of the annular section V-shaped damper cylinder barrel 6 are fixedly provided with a circular cylinder barrel cover plate 10, six fan-shaped annular pore canals 9 which are uniformly distributed along the circumferential direction are engraved on the lower surface of the circular cylinder barrel cover plate 10, a circular cylinder barrel chamber 8 is formed by enclosing the piston rod 5, the inner cylinder body 2, the cylindrical piston 3 and the cylinder barrel cover plate 10, and the circular cylinder barrel chamber 8 is communicated with the annular section V-shaped damping channel 4 through the fan-shaped annular pore canals 9; the upper end parts of the piston rods 5 on the left side and the right side are respectively connected with a steel wire rope 11, the upper surfaces of the round cylinder barrel cover plates 10 are respectively connected with a steel strand 12, the peripheries of the steel wire ropes 11 and the steel strand 12 are respectively provided with a metal corrugated pipe 13, and the upper ends of the steel wire ropes 11 and the steel strand 12 are respectively anchored on a reinforced concrete shear wall body 21 through anchor plates 14.
In order to increase the tightness between the cylindrical piston 3 and the inner cylinder body 2, an annular sealing groove is formed in the outer side of the cylindrical piston 3, and an O-shaped sealing ring 7 is arranged in the annular sealing groove.
The high-strength reinforcement 22 is a steel strand or a fiber reinforced composite reinforcement; in the energy-consumption shear wall with double self-recovery capability, the concrete shear wall at the lower part of the left side is positioned as the point A, the anchoring point of the anchor plate at the upper part of the left side is B, the anchoring point of the anchor plate at the upper part of the right side is C, the concrete shear wall at the lower part of the right side is positioned as the point D, and the lower end fixed point of the annular section V-shaped damper cylinder barrel (6) is E.
In order to reduce the elastic deformation of the wire rope 11 and to convert the relative displacement between the shear walls BE (or CE) into the relative displacement between the annular cross section V-shaped damper cylinder 6 and the piston rod 5 as much as possible, the wire rope 11 needs to BE prestressed.
The working principle of the invention is as follows:
under the action of horizontal earthquake load, the shear wall structure can generate interlayer relative displacement, the left and right end points B, C on the upper part of the shear wall body can generate reciprocating horizontal relative displacement relative to the point E on the lower part, and the distance between the two points BE can BE prolonged or shortened. When the distance between the two points of BE is lengthened (at this time, the distance between the two points of CE is shortened). Since the annular section V-shaped damper cylinder 6 is fixed at the point E, the wire rope is connected to the point B (or point C) and the end of the piston rod, and the wire rope is pre-stressed, the wire rope 11 converts the relative displacement between the shear wall BE (or CE) into the relative displacement between the annular section V-shaped damper cylinder 6 and the piston rod 5. The volume in the annular column chamber 8 at the upper part of the left side of the damper is reduced, damping energy consumption materials flow into the annular column chamber at the upper part of the right side of the damper through the fan-shaped annular pore canal 9 and the annular cross section V-shaped damping channel 4, and the piston rod at the right side of the damper approach to the E point under the action of liquid pressure. When the distance between the two points CE is lengthened, the volume in the annular cylinder chamber 8 at the upper right side of the damper is reduced, and damping energy dissipation materials flow into the annular cylinder chamber at the upper left side of the damper through the fan-shaped annular pore canal 9 and the annular cross-section V-shaped damping channel 4. Therefore, when an earthquake happens, the damping energy consumption material flows back and forth in the V-shaped damping channel with the annular section, so that damping force and energy dissipation and shock absorption effects can be generated, thereby effectively consuming the earthquake energy transmitted into the building structure, reducing the dynamic response of the structure under the action of earthquake load and improving the earthquake resistance of the building structure.
The high-strength bars 22 arranged on the left side and the right side of the reinforced concrete shear wall body 21, the connecting point B (or the point C) and the steel stranded wires 12 of the round cylinder cover plate 10 have high tensile strength, and the structure is always in an elastic working state under the strong shock effect. Therefore, when the structure has residual deformation after strong earthquake, the distance between AB (or CD) and BE (or CE) is elongated due to the residual deformation, the high-strength reinforcement 22 and the steel strands 12 generate elastic restoring force due to the elongation, and the reinforced concrete shear wall body is quickly pulled back to the original position due to the double restoring force, so that the residual deformation is small, and the structure has double restorability.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the invention.
