Description
Technical field
The utility model relates to Anti-quake Architectural Structure Design field, especially relates to a kind of pressure and draws the unidirectional buckling restrained brace device of weak type.
Background technology
Early stage earthquake engineering worker is in order to alleviate and avoid earthquake disaster, study and formulated a set of comparatively complete Struture Earthquake Resistant Theory and method, by carrying out the Seismic Bearing Capacity checking computations under frequently occurred earthquake to structure and the elastic-plastic deformation checking computations under rarely occurred earthquake ensure structural seismic performance, the Seismic Design Requirements of " no damage in small earthquake, middle shake can be repaiied, shake greatly less than " reaching.Traditional method of seismic design method ensure that supporting capacity and the ductility of structure to a great extent by the anti-seismic performance strengthening structure itself, can alleviate structural deterioration and casualties when coming earthquake.But because the method is by the dissipation seismic energy of structure own, and the data information of traditional design method comes from the summary that a situation arises of earthquake in history, so when being still not clear the intensity of Future Earthquakes disaster and characteristic, the structure traditionally designed lacks capacity of self-regulation, probably cannot meet the requirement of safety.
Structural seismic control is the comparatively obvious antidetonation approach of current effect, and concrete grammar by adding control device, device and structure is consumed energy jointly, to alleviate the earthquake response of structure, reaches the object avoided or postpone agent structure and destroy.Passive Control is be suggested the earliest and is be considered to the most at present and the control method the most easily implemented, and it comprises base isolation and energy-dissipating and shock-absorbing two class mode.This control method of energy-dissipating and shock-absorbing allows seismic energy toward structure transmission, but in superstructure, be provided with specific energy-dissipating device (damper), be transferred to energy-dissipating device to dissipate the seismic energy major part of agent structure consumption originally should be had, greatly alleviating structure self due to plasticity consumes energy the damage produced, effectively avoid structure major injury occurs in earthquake and collapses, therefore this technology has good economy and application prospect.
Anti-buckling support is widely used in structural seismic control at present as a kind of novel special damper, has good anti-seismic performance and very strong engineer applied.Anti-buckling support is a kind of support form having common support and metal yield energy-consumption damper dual-use function concurrently, not only solve common support causes structure to form the problem of weak floor after easy compressive buckling and flexing under large shake, also play the effect of Damage Coutrol simultaneously, make originally to be changed into by the power consumption mode of agent structure beam-ends formation plastic hinge (damage) to concentrate power consumption on anti-buckling support component, and agent structure major part keeps elasticity, thus agent structure (beam can be protected preferably, post) make it in the middle of large shake from major injury, the anti-seismic performance not only increasing structure solves again the rear problem of repairing of shake.
Three levels that China current aseismic fortification objects adopts " no damage in small earthquake, middle shake can be repaiied, shake greatly less than ", should be able to ensure when being subject to rarely occurred earthquake effect not collapse according to this claimed structure.According to the earthquake that " seismic design provision in building code " (GB50011-2010) rarely occurred earthquake is 1700-2500 mono-chance, specification gives horizontal earthquake influence coefficient and specifically considers rarely occurred earthquake effect, but this coefficient be draw according to statistical value can not ensure that Future Earthquakes intensity is no more than this value, when therefore calculating the Antiseismic building of particular importance, horizontal earthquake influence coefficient value should be higher.Rarely occurred earthquake belongs to small probability event, be used for ensureing that the safety of structure not only can significantly improve construction cost to be also unnecessary sometimes by improving design earthquake, such as to this kind of special Important building of nuclear power station steam turbine factory building can by regulation and stipulation seismic fortification intensity consideration geological process ensure nuclear island safety in extreme circumstances away from nuclear island by certain measure control structure exceeding the collapse direction under geological process of setting up defences simultaneously.
