Description
Technical field
The present invention relates to structure with energy dissipation devices and analytical technology in building structure technology field, particularly relate toAnd the energy-dissipating and shock-absorbing structure sinker envelop optimization method of the additional effective damping ratio of a kind of based target.
Background technology
The antidetonation of traditional architecture structure mainly occurs that by structure and member damage consumes seismic energy in earthquakeAmount, and the badly damaged of structure and member is exactly conversion or the consumption process of seismic energy. In recent years, along withChina's earthquake takes place frequently, and causes building structure subject to severe risks of damage, is endangering people's life and property safety. Due toAt present the mechanism of structure " firmly anti-" earthquake is difficult to arrive effective control requirement, therefore " soft anti-" earthquakeThe extensive use gradually in building structure of mode-energy-dissipating and shock-absorbing technology, it is to complicated building structure and lifelineEngineering has great significance.
Energy-dissipating and shock-absorbing technology is a kind of dissipate Passive Control skill of seismic energy of sinker that arranges in building structureArt. Energy-dissipating and shock-absorbing structure comprises agent structure and energy dissipation component, and energy dissipation component is by sinker with for agent structureConnect the member composition of sinker. Sinker by internal material or and member between friction, utilize elastoplasticityHysteresis distortion or glutinous (bullet) property hysteresis are out of shape to dissipate or absorb seismic energy. In brief, energy-dissipating and shock-absorbing skillArt is exactly, at some position of major structure of construction, sinker is set, and is out of shape to dissipate or to absorb earthquake defeated by itEnter the energy of structure, to reduce the impact on agent structure, thus protection agent structure. Conventional sinker hasDisplacement relationship type sinker, velocity correlation type sinker and compound sinker etc.
The Performance Design of energy-dissipating and shock-absorbing structure is for overall structure, partial structurtes, energy dissipation component, crucial portionPosition, important component, secondary member etc. are set corresponding performance objective, according to the performance objective of setting, energy dissipating are subtractedShake structure is analyzed design, and key is reasonably to select and to arrange energy dissipating in structure with energy dissipation devicesDevice, brings into play the energy dissipation behavior of sinker to greatest extent, and the performance indications of weighing sinker energy dissipation capacity are exactly itAdditional effective damping ratio. The additional effective damping ratio of target of sinker is the energy-dissipating property target of sinker, disappearsType that can device, select quantity, arrangement form and position all can affect sinker entirety energy dissipation behavior, enterAnd affect the realization of its performance objective.
In the Performance Design of energy-dissipating and shock-absorbing structure, the selecting and arrange that basic to meet target additional of sinkerThe requirement of effective damping ratio, but often exist energy dissipation component type to select unreasonable, quantity to use too much, arrangeThe irrational defect in form and position, exchanges its work quality for to increase the quantity of sinker, causes sinkerIn energy-dissipating and shock-absorbing structure, in inefficient duty, this just need to be optimized design to sinker,Select rational sinker type, determine its quantity, arrangement form and position, thereby realize sinker shock resistanceTechnology and the economic rationality of energy target.
At present, the performance-based optimal design of existing energy-dissipating and shock-absorbing structure adopt based on displacement performance targetSinker Optimization Design, it is substantially with relative storey displacement or the relative storey displacement angle of each floor of major structure of constructionAs performance objective, thereby sinker is optimized to control, sets multiple sinker arrangement, make main bodyStructure meets and progressively approaches the displacement performance targets at different levels that little shake, middle shake and large shake are set, and therefrom determines a kind ofThe arrangement of sinker.
But there is following defect in the performance-based optimal design of this energy-dissipating and shock-absorbing structure:
(1) it is from the displacement macroparameter index of major structure of construction, and its essence object is to control energy-dissipating and shock-absorbingThe distortion of structure, the position of sinker is only just adjusted in the optimization of sinker, seldom relates to even and not havingQuantity to sinker and arrangement form aspect are optimized, cause sinker in energy-dissipating and shock-absorbing structure in lowThe duty of efficiency, although can substantially reach the technical index of sinker design in structure with energy dissipation devices,But cannot meet economic index.
(2) its essence object is to control the distortion of energy-dissipating and shock-absorbing structure, and therefore, this optimization method is only limited to toolHave the multilayer structure of layer concept, and and be not suitable for without the absolute large public building of layer concept, as greatlyType stadiums, airport, station etc., so can not be applicable to all construction styles.
(3) it,, not from the energy dissipation behavior of sinker itself, has ignored energy-dissipating and shock-absorbing structure in the time of geological processThe variation of its structural response is because sinker dissipation seismic energy provides additional effective damping ratio, andBe only the optimization of carrying out sinker based on displacement structure parameter, so, make energy-dissipating and shock-absorbing structural seismic performance orderIt is abundant not that mark technical and economic requirements is realized, and also fails to embody the substantive characteristics that sinker is optimized, and causes and disappearThe optimization efficiency of energy device is low, and effect of optimization is not obvious.
