【正文】 rthquake 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 of the purpose to the beneficial breakage mechanism is to the structure and break mode, avoid not reasonable of the structure break appearance, and try assurance to anticipate to break part to play plasticity to transform an ability. The ability design method mainly passes the following three kinds of measure to give assurance: 1. Enlarge pillar opposite in the anti of the beamcurved ability, artificial of leading of the structure swing joint part. 2. Raise opposite in is cut the noodles loading dint of the anti shear ability, avoiding appearing non ductility to shear to slice breakage. 3. To the part that appears the plasticity swing probably, the adoption corresponds of structure measure, assurance necessity of not flexible transform function. First, the reasonable part of the swing joint carry on a discussion, all countries mostly of the way of thinking inclines toward to make the project that the beam carries first to carry to appear in the pillar about and all. This kind of swing joint project has a following advantage: The ductility of the beam is easy to a control, and under general circumstance pare pillar of the ductility is big。t very strong, can also guarantee structure generally under the big earthquake of not flexible transform of function。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。 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。 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。s taking the basic problem of the value size have to arrive understanding definitely, be the anti earthquake the earthquake dint take a value of the size isn39。t don39。s last century, the New mark passed to start to the beginning of different period just degree homology of the single freedom degree the system carried on analysis under the situation that many waves input, put forward etc. moved the principle and etc. energy principle, and put forward the concept of the structure ductility. Studied single and free system to accept defeat the level and flexibility thoroughly again from the relation of flapped the biggest not flexible motive in the period and structure to respond afterward, this be customarily say of the theories of the Rμ T effect. Passing these researches, announcing to public the ductility ability and plasticity to consume an ability is a structure Be taking to use to accept defeat level under not high circumstance, at big earthquake under the structure doesn39。s detection putes to gain from here of the structure respond with the actual earthquake the breakage phenomenon of the structure contain
