Description

Double X-type friction-yield steel energy dissipator
Technical field
The utility model belongs to building engineering structure anti-seismic technology field, relates to a kind of double X-type friction-yield steel energy dissipator.
Background technology
In recent years, China has obtained plentiful and substantial achievement in research having carried out number of research projects aspect shock insulation, vibration damping and the vibration isolation of engineering structures.Traditional seismic design is to resist geological process by the anti-seismic performance that strengthens structure itself, promptly stores and earthquake energy with structure itself, and to satisfy the structural seismic standard of setting up defences: little shake is not bad, and middle shake can be repaiied, no collapsing with strong earthquake.And this antidetonation mode lacks capacity of self-regulation, under uncertain geological process, does not satisfy the requirement of safety probably, and the energy-dissipating and shock-absorbing technology provides a rational and effective approach for structural seismic.Its main thought is absorbed the energy dissipator that the seismic energy of input structure is guided special setting into and is dissipated, thus the safety of protection agent structure.Metal yield sinker and friction sinker are two kinds of common energy dissipators, absorb seismic energy by frictional behavior between plastic property behind the metal yield and the metal, the category that belongs to the Passive Control system, its advantage mainly is: energy-dissipating property stablizes, is easy to change, economic, practical, draw materials simply, adopt common steel to process usually.Its weak point is: lack the self-adjusting ability of control, can not adjust the size of sinker control according to building structure at the response characteristic under the geological process.
The destruction of earthquake disaster has Unpredictability; building structure suffers geological process not of uniform size; energy dissipator is as a kind of novel damping method in building aseismicity field; aspect power consumption, should import the size of energy and difference according to earthquake; as the less control that adapts to it can be provided under little shake effect; the whole abilities of performance energy dissipator consume energy under middle shake, big shake effect, protect agent structure more fully, and then echo mutually with the three stage criterions of providing fortification against earthquakes.The utility model is cascaded metal yield and friction sinker, to realize the self-regulation and the function that consumes energy stage by stage, the metal yield damper that wherein relates to adopts the inventor to declare " double X-type mild steel damper " (number of patent application: 200410020892.8) of invention before, the utility model has tangible difference with the invention of declaring before, not only possesses the advantage that initial stiffness is big, energy dissipation capacity is strong that the double X-type mild steel damper is had, and by with the use of connecting of frcition damper, realize self-regulation, the function that consumes energy stage by stage.
Summary of the invention
The utility model provides a kind of double X-type steel surrender-friction sinker, its objective is that the power consumption effect that solves energy dissipator is single, lacks the adjustability problem.
The technical solution of the utility model is as follows:
A kind of double X-type friction-yield steel energy dissipator is connected steel plate and is formed by power consumption steel plate, last friction steel plate, following friction steel plate, level.It is characterized in that: power consumption steel plate plane is made trapezoidal, stacked placement, power consumption steel plate upper and lower side is connected steel plate with following friction steel plate and level respectively and connects as one by welding manner, last friction steel plate is offered conduit, to go up friction steel plate with bolt is connected with following friction steel plate, the mild steel of tensile yield strength smaller or equal to 235Mpa is chosen in the suggestion of power consumption steel plate materials, has good plastic property to guarantee it.It should be noted that: the first, the power consumption steel plate is processed into two X-shaped shapes makes it the phenomenon of multiple spot surrender occur in the stressed stage, thereby has improved the distortion energy-dissipating property of damper greatly, two X geometries of the steel plate that will guarantee to consume energy in design physical dimension process; The second, double X-type steel surrender-friction sinker stress form is stressed in the plane.The 3rd, to concentrate for avoiding stress, the wedge angle that the power consumption steel plate occurs all replaces with the fillet form.The four, two friction steel plate contact surface adopts machining, guarantees that surface of steel plate is smooth, full contact.
Effect of the present utility model and benefit are mainly reflected in the self-regulation of double X-type friction-yield steel energy dissipator and stage by stage on the energy dissipation behavior: by adjusting the length of double X-type friction-yield steel energy dissipator friction steel plate hole slot, realize stage friction energy-dissipating just; When the hole slot length of displacement deformation above setting, then metal power consumption steel plate generation plastic strain is consumed energy by the plastic deformation performance.Stage power consumption just can realize controllability by hole slot length, realizes the next stage power consumption by metal yield after reaching the limit of displacement.The particularity of double X-type friction-yield steel energy dissipator makes the seismic design process more convenient, practical, will more be widely used in the Anti-quake Architectural Structure Design field.
