Description
Technical field
The utility model relates to a kind of curvature-prevention support component, specifically a kind of viscoplasticity-buckling-restrained energy-dissipation.
Background technology
Viscoelastic damper can for structure certain rigidity is provided while larger damping is provided; Its power and displacement lagging curve approximation are in ellipse, and energy dissipation capacity is strong, and the wind that can effectively reduce building shakes and earthquake response.Compared with displacement relationship type damper (such as buckling-restrained energy-dissipation), viscoelastic damper can consume energy under all vibration conditions, even if under less vibration condition, also can consume energy.It needs larger relative displacement unlike hysteresis energy consuming device (as metal energy-dissipating device and friction energy consuming device) could there is yield deformation or overcome friction to play their power consumption effect.So viscoelastic damper can simultaneously for earthquake and the wind dynamic control of structure, turn avoid the problem how energy consumer initial stiffness that other power consumption (damping) device exists matches with lateral displacement stiffness of structure.
In prior art, anti-buckling support is that a kind of axis pressure by steel draws catabiotic displacement relationship type damper, it is primarily of core unit in anti-buckling support and restraining tube constraint mechanism composition, interior core unit and restraining tube is inter-agency leaves gap or adopt non-cohesive material to fill.Anti-buckling support inner core is as axially loaded component, it is under the lateral restraint of peripheral constraint mechanism, when the effect of under tension and pressure, all can reach the abundant surrender of total cross-section, the seismic energy of input structure can be consumed better, thus play the effect of energy dissipation.
Desirable anti-buckling support requires that its performance is: one is low surrender, to guarantee just can consume energy under little shake; Two is that energy dissipation capacity is large, to ensure the effect that also can reach damping power consumption under large shake; Three is that deflection is large, to adapt with the stratified deformation of the building under geological process.
But, in actual implementation process, anti-buckling support has following two problems: one is because buckling-restrained energy-dissipation belongs to displacement relationship type dissipative member, relevant with agent structure relative storey displacement size, when structure is under little shake state, structure relative floor displacement is less, be difficult to reach buckling-restrained energy-dissipation yield story drift, component is in elastic stage, the re-set target consumed energy can not be realized, the inertia force because little shake produces and structural vibration cannot be cut down, wind load cannot be cut down in normal conditions of use simultaneously, the structural vibration that outdoor environment etc. cause.Two is that anti-buckling being supported for the while that structure adding rigidity has attached certain weight, so just needs agent structure to bear consequent gravity and Earthquake Inertia Force Acting, increases the stressed of agent structure., vibration source higher for instructions for use (as little sidesway, micro-vibration etc.) is comparatively strong but have vibration damping demand, or need to guarantee building function under moderate (as fortification intensity) earthquake, simultaneously, when needing to ensure excellent anti-seismic performance under rarely occurred earthquake, the anti-buckling support technology of single use is just difficult to accomplish that both have taken into account.
