The specific embodiment
Shown in Fig. 1~4, a kind of viscoplasticity-soft steel shearing type combined energy comsuming device 10 comprises viscoelastic damper and shear energy dissipation combination plate.Shear energy dissipation combination plate comprises horizontal baffle 3, power consumption web 5 and connects end plate 6, horizontal baffle 3 and the up and down two ends that are connected end plate 6 and are individually fixed in the web 5 that consumes energy, and present embodiment employing welding manner is fixed.Viscoelastic damper is located on the horizontal baffle 3, comprise by U-shaped cover plate 1 and between U-shaped cover plate 1 and horizontal baffle 3 viscoelastic damping interlayer 2.Sulfuration bonding between visco-elastic damping layer 2 and U-shaped cover plate 1 and the horizontal baffle 3.
The length of U-shaped cover plate 1 is greater than the length of viscoelastic damping interlayer 2, surround viscoelastic damping interlayer 2, so that shear strain when occuring in visco-elastic damping layer 2, the displacement range of visco-elastic damping layer 2 is limited in the length range of U-shaped cover plate 1, to prevent that visco-elastic damping layer 2 from surpassing the maximum distortion degree, causes combined energy comsuming device to damage.
As shown in Figure 4, also be provided with frange plate 7 and stiffening rib 8 on the power consumption web 5.Frange plate 7 vertically arranges, and is symmetrically fixed on power consumption web 5 both sides, and stiffening rib 8 is level and vertical the setting respectively, is fixed on the plate face of power consumption web 5.In the present embodiment, frange plate 7 and stiffening rib 8 adopt welding manner to be fixed on the power consumption web 5.When power consumption web 5 produces in the planes shear strain, flexing outside the plane appears in order to delay it, the degeneration of strength and stiffness appears in the web 5 of avoiding consuming energy, so at power consumption web 5 stiffening rib 8 is set, flakiness ratio with the web 5 that reduces to consume energy, guarantee that it fully develops elastic-plastic deformation before flexing, form stable shear energy dissipation mechanism.Frange plate 7 can retrain power consumption web 5 borders and rotate, and is bent and deformed and bears Partial Shear.
U-shaped cover plate 1, horizontal baffle 3, connection end plate 6 and vertical frange plate 7 are made by the steel that yield strength is not less than 235MPa, and its size should satisfy the rigidity requirement.Power consumption web 5 is made by the mild steel that is not more than 235MPa, and its size is according to the Structural Energy Dissipation Location of requirement.Visco-elastic damping layer 2 is macromolecule polymer material, and with U-shaped cover plate 1 and horizontal baffle 3 sulfuration bondings, its size is determined according to shock attenuation needs.Stiffening rib 8 requires to design according to power consumption web 5 anti-flexings.
Laterally be provided with shock-absorbing spring 4 between the biside plate of U-shaped cover plate 1 and the horizontal baffle 3.Shock-absorbing spring 4 connects U-shaped cover plate 1 and horizontal baffle 3.In the present embodiment, shock-absorbing spring 4 is the steel spring, and two ends are connected with U-shaped cover plate 1 and horizontal baffle 3 respectively.The initial length of shock-absorbing spring, i.e. horizontal clearance distance between U-shaped cover plate 1 and the horizontal baffle 3 depends on distortion limit value and the shear plate yield displacement of viscoelastic material, the rigidity of shock-absorbing spring should design according to visco-elastic damping layer power consumption demand.Between U-shaped cover plate 1 and horizontal baffle 3, shock-absorbing spring 4 is set, both can have increased the damping effect of combined energy comsuming device, prevent simultaneously in the work, the collision that U-shaped cover plate 1 and horizontal baffle 3 occur owing to horizontal relative motion.
Below in conjunction with the scheme of installation of the utility model in frame construction operating principle of the present utility model is described.
As shown in Figure 5, among the first embodiment, the utility model is chosen the column arrangement form, and namely viscoplasticity-soft steel shearing type combined energy comsuming device 10 is connected on the Vierendeel girder by two pillars 20 up and down, is installed on the centre position of story height.
Such as 6 and shown in Figure 7, among the second embodiment, the utility model is chosen the brace type arrangement form.Among Fig. 6, viscoplasticity-soft steel shearing type combined energy comsuming device 10 is connected on the framework by diagonal brace, can be arranged between Vierendeel girder bottom and the herringbone support, top; The utility model adopts the X-type supporting form to be arranged in the centre position of story height among Fig. 7.
Both compare, and brace type arrangement form elastic stiffness is relatively large, can guarantee the larger energy dissipation capacity of combined energy comsuming device performance.It is less that the column arrangement form takies architectural space, can satisfy the current requirement in bottom.
Among the first and second embodiment, the utility model can mode with bolts or welding assemble.Particularly, the pillar shown in Fig. 5 to Fig. 7 20 or diagonal brace 30 at first are connected with pre-buried parts on the Vierendeel girder.Then the U-shaped cover plate 1 of viscoplasticity-soft steel shearing type combined energy comsuming device 10 be connected end plate 6 on have screw, the end plate that is connected by high-strength bolt auxiliary connection and pillar 20 or diagonal brace 30 links to each other, and to realize installation of the present utility model, guarantees Shear transfer.In practical set, also can realize that the utility model links to each other with pillar 20 or diagonal brace 30 by the mode of welding, perhaps after with bolts, by welding further reinforcement bonding strength.Because two kinds of arrangement forms all adopt site assembly, quality is easy to control, is convenient to damaged replacement.
After installing, when external drive causes the framework relative floor displacement, U-shaped cover plate 1 produces reciprocal relative motion with horizontal baffle 3, drive visco-elastic damping layer 2 and produce the shearing lag return distortion, damping force is provided, simultaneously respectively axial tension and extruding of both sides shock-absorbing spring 4, the power consumption web then keeps elastic stage.When relative storey displacement increases to a certain degree, when shock-absorbing spring 4 reaches the axial deformation limiting value, be that visco-elastic damping layer 2 shear strains reach pre-set limit, at this moment, U-shaped cover plate 1, visco-elastic damping layer 2, horizontal baffle 3 and shock-absorbing spring 4 will be done as a wholely to produce relative motion with being connected between the end plate 6, drive power consumption web 5 and produce shear strain, and formation shear yielding, after the relative displacement increment between U-shaped cover plate 1 and the horizontal baffle 3 changes direction, visco-elastic damping layer 2 produces the flip Trim distortion, and so forth, visco-elastic damping layer 2 and 5 collaborative works of power consumption web, vibrational energy by in the shearing lag return distortion dissipation input structure destroys thereby alleviate agent structure, realizes energy-dissipating and shock-absorbing (shaking) purpose of the first embodiment.
Viscoplasticity provided by the utility model-soft steel shearing type combined energy comsuming device 10, viscoelastic damper and the collaborative work of shear energy dissipation combination plate, by the vibrational energy in the shearing lag return distortion dissipation input structure, destroy thereby alleviate agent structure, realize that the utility model controls simultaneously that wind shakes and the purpose of damping.
The above-mentioned description to embodiment is can understand and use the utility model for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the utility model is not limited to the embodiment here, and those skilled in the art are according to announcement of the present utility model, and not breaking away from the improvement that the utility model category makes and revise all should be within protection domain of the present utility model.
