【文章內(nèi)容簡介】 chanism related quantity value. Here what to need to be explain BE, designed the earthquake dint to take a value to resolve a problem only, but to the structure ductility function guarantee of the measure have to can also promise, this will at underneath a section discuss. Currently, the anti earthquake norms all round the world almost adopts so a kind of way of thinking: The adoption presses the earthquake strong or weak of possible situation to divide the line earthquake cent area。 According to everyplace the history occurrence of the area earthquake of covariance result or to geology structure of the history investigate to have to explicit statistics the meaning establish the sport peak value in waterproof and quasi ground value acceleration。 Make use of again the reaction acceleration that the acceleration reaction poses different period to descend structure to。 get a design to use acceleration level through the earthquake dint adjustment coefficient R. In the meantime, most nations all approve such standpoint, establishing to defend the earthquake intensity level can take to use a different value, choosing to use to establish to defend the earthquake intensity level more and highly, the ductility request of the structure also more low, choose to use to establish to defend the earthquake intensity level more and lowly, structure of ductility request more high. The structure ductility guarantee of precondition is the ductility of the member, pass again an effectively reasonable conjunction in adopting a series of measure guarantee member the foundation of the ductility, the structure system choice is reasonable in the meantime, the degree just distributes reasonable of under condition ability basic assurance structure of ductility. Underneath this kind of discusses the our country anti earthquake norm mostly way of thinking, the current Chinese norm didn39。t adopt a variety to establish to defend the earthquake intensity level to take to use, but don’ Ted add 中國石油大學(xué)（華東）本科畢業(yè)設(shè)計（論文） 9 a distinction of unify an adoption of the earthquake dint adjustment coe fficient R=1/。In the meantime, mostly according to establish a dissimilarity of defend the earthquake intensity, divide the line the different anti earthquake grade, fix attention on in establish to defend earthquake intensity differently, adopt the anti earthquake measure of the different assurance ductility. Very obvious here exist a misunderstanding of concept, also be according to the theories of the Rμ T effect, the little more than earthquake dint adjustment coefficient R=1/, should give the same ductility guarantee measure to the structure, but the Chinese norm adopt the different ductility guarantee measure, along with anti earthquake the exaltation of the grade, ductility guarantee the ability correspond to strengthen. This kind of usefulness of the way of doing under way and not the line motive respond of verification, can describe so as a result mostly: For the district of 8 degrees g and 9 degrees g, because of correspond of the anti earthquake grade is higher, the measure of the guarantee ductility is also stronger, so generally and more safe。 And for the district of 6 degrees g and 7 degrees g, gain from here to of the level earthquake effect be partial to small, the general lotus carries an array, group is carried the control function by the gravity lotus, although to should of the measure of the guarantee ductility isn39。t very strong, can also guarantee structure generally under the big earthquake of not flexible transform of function。 But to the district of 7 degrees g and 8 degrees g, circumstance another the person worry, because of at the lotus carry an array, group, the earthquake function can have generally control function, but correspond measure of guarantee the ductility and be partial to weak, so difficult don39。t need to exist certain potential safety hazard to suffer from. See again other national earthquake dint adjustment coefficient R to choose to use, in order to have kept concrete understanding of view: 中國石油大學(xué)（華東）本科畢業(yè)設(shè)計（論文） 10 The earthquake dint adjustment coefficient of all countries norm provision European mon body EC8 New Zealand NZS3101 American UBC1997 Chinese GB50011 2021 The DCL low ductility The flexibility responds structure General frame 1/ ≈s In the DCM ductility Limited ductility structure Medium frame The DCH high ductility Ductility structure Special frame 3． Ability Design Method Top a part emphasized to discuss the design earthquake dint to take the problem of the value, but wanted to promise structure under the big earthquake of function, also need to establish the valid anti earthquake measure, make the structure really have need of keep vertical loading under the dint condition not flexible transform an ability, this be the socalled ability design method. Ability design method from New Zealand the reinforced concrete anti earthquake expert scholars such as the T. Parlay and the R. Park etc. development with initiate, main way of thinking is to the member occasionally member dissimilarity inside the piece is subjected to the dint form of the loading ability differ of control, promise the reinforced concrete structure formation the beam swing joint anization and ductility bigger is cut noodles to be subjected to the dint breakage appearance, make the structure have to play plasticity to transform function enough, promise big earthquake hour have an enough ability to consume to spread function, avoid creation brittleness to break and appear 中國石油大學(xué)（華東）本科畢業(yè)設(shè)計（論文） 11 disadvantageous of anization form. The key of the ability design method is the anti earthquake design that leads the control concept into structure, there is the leading formation o
