Description

A kind of energy consumer stage by stage
Technical field
The utility model relates to the field that prevents vibration in construction work, particularly a kind of for suppress engineering structures earthquake and wind bestir oneself with under the vibration absorber of structural vibration response.
Background technology
Low-yield steel have lower yield point, are conducive to energy consumer and enter surrender power consumption prior to structural element, and have good plasticity, ductility and Hysteresis Behavior, therefore have good stable energy dissipation capacity.Due to above-mentioned advantage, Low Yield Point Steel is particularly suitable as antidetonation steel, and is progressively subject to approval and attention in the industry, has now become new steel grade and the emphasis steel grade of steel for antidetonation.Along with 20 the end of the century the rising gradually and the development and application of Passive Control theory of low-yield Steel material, Low Yield Point Steel energy consumer starts to be widely used in during the transformation reinforcing of existing building and the energy-dissipating and shock-absorbing of new building design.Up to the present, existing polytype Low Yield Point Steel energy consumer comes out.
Along with industry development, the anti-fatigue performance of existing Low Yield Point Steel energy consumer usually can not meet the high request of modern architecture, also exposes complex structure simultaneously, the also comparatively loaded down with trivial details problem of changing is installed, and much all have the defect that cost is higher.
Utility model content
The technical problem solving: for the deficiencies in the prior art, the utility model proposes a kind of energy consumer stage by stage based on Low Yield Point Steel, solve traditional Low Yield Point Steel energy consumer and resist tired power poor performance, complex structure, installation to change the technical problem loaded down with trivial details, cost is high.
Technical scheme: for solving the problems of the technologies described above, the utility model by the following technical solutions:
An energy consumer, comprises parallel relative top board and base plate stage by stage, is provided with power consumption steel disc in the middle of described top board and base plate, and described power consumption steel disc connects top board and base plate; Described power consumption steel disc comprises a first stage power consumption steel disc and two the second stage power consumption steel discs that are arranged in parallel, described two second stage power consumption steel disc be take first stage power consumption steel disc and is arranged on its both sides as center line, and the width of described first stage power consumption steel disc is greater than the width of second stage power consumption steel disc; The yield point of the material of described first stage power consumption steel disc is lower than the yield point of the material of second stage power consumption steel disc; Described power consumption steel disc is provided with the hole of parabolic, and openings of sizes one group of parabola identical and that opening is relative between two forms the hole of a parabolic, and parabolical axis of symmetry is parallel to top board and is positioned at the centre position of power consumption steel disc; The hole of the parabolic on first stage power consumption steel disc is greater than the hole of the parabolic on second stage power consumption steel disc.
The size that is positioned at the second stage power consumption steel disc of both sides in the utility model is less than middle first stage power consumption steel disc, be positioned at the also mutually deserved parabola opening being positioned on first stage power consumption steel disc that is less than of parabola opening on second stage power consumption steel disc simultaneously, in the selection of material, first stage power consumption steel disc yield point is lower than the yield point of second stage power consumption steel disc, more than arrange and cause two kinds of power consumption steel discs to there is different initial anti-side rigidity, thereby there is different yield displacements and yield load, thereby can realize power consumption stage by stage.Under little shake effect, the plastic yielding power consumption that takes the lead in of middle first stage power consumption steel disc, under large shake effect, the second stage power consumption steel disc of both sides also progressively enters plastic state, participates in power consumption work; To the hole of several parabolic be set on power consumption steel disc simultaneously, the paper < < parabolic profile mild steel damper experimental study > > delivering at < < building structure journal > > according to Xu Yanhong, Li Aiqun, Huang Zhen in 2011, the hole of parabolic is conducive to consume energy even development and the distribution of steel disc plastic strain, thereby has good Hysteresis Behavior and anti-fatigue performance.
As preferably, in the utility model, the material of first stage power consumption steel disc is Low Yield Point Steel; The material of second stage power consumption steel disc is common straightcarbon steel.Low Yield Point Steel is the general designation of the steel that yield point is lower, generally all has good deep drawability and deep-drawing performance, compares with carbon steel, and low-yield yield of steel is lower.
The utility model is when selecting power consumption steel disc, guarantee yield displacement appropriate of first stage power consumption steel disc, if yield displacement is too little, can cause the frequent first stage power consumption steel disc of changing of needs, if contrary yield displacement is too large, the yield displacement of two stage power consumption steel discs is not obvious respectively, also cannot realize the object that this device consumes energy stage by stage.Here the size of yield displacement main with the size of Wasted-energy steel plate, the material of the size of parabola opening and the steel disc that consumes energy is relevant, specifically can select by finite element analysis or experimental study the combination of suitable power consumption steel disc.
As preferably, in the utility model, described power consumption steel disc and top board and base plate are all by being welded to connect.Guarantee that power consumption steel disc is connected with top board and the reliable of base plate.
Further, in the utility model, on each power consumption steel disc, interval arranges the hole of parabolic, and the position of two parabola docking of same group arranges fillet.The hole of even spaced parabolic, the stressed rear homogeneous deformation of the steel disc that makes to consume energy, and fillet setting can prevent that stress is concentrated.
Further, in the utility model, the left and right edges of power consumption steel disc is all arranged to the opening parabolic of self dorsad.Corresponding with the hole of parabolic, the steel disc that makes to consume energy arranges in hole and the entity part interval of parabolic on the whole, is conducive to plastic strain and evenly develops.
Further, in the utility model, prepared screw-bolt hole on top board and base plate, is connected with main structure body by high-strength bolt or shear connector.Guarantee that this device is reliably connected with main structure body, brings into play cushioning effect under horizontal force.
Beneficial effect:
The novel Low Yield Point Steel that the utility model provides a kind of and designed and produced simply, installation is changed conveniently, Hysteresis Behavior is stable, cost is relatively cheap and can consume energy is stage by stage energy consumer stage by stage;
This energy consumer utilizes two kinds of power consumption steel discs with different yield displacements and yield load to realize power consumption stage by stage, and parabola shaped punching is conducive to even development and the distribution of its strain, thereby makes it have good Hysteresis Behavior and fatigue behaviour;
This energy consumer is arranged in building structure, and a large amount of energy that can dissipate under little shake and large shake, plays considerable damping effect.
