According to the request of the ability design, the plastic hinge that shears the dint wall appears generally in the bottom of the wall limb. The joining beam shear the loading dint and ductility that the loading dint and ductility and entrance to cave of the dint wall connect beam contain very great relation, designing generally and possibly weak connect beam, the leading that has intention to know connects beam at earthquake accept defeat first, then is the bottom wall to accept defeat, also be anticipate the area of plastic hinge to accept defeat. Avoided appearing to shear reason of slice the breakage early easy, be because of shearing to slice to break to belong to the brittleness breakage, disadvantage in promise the ductility of the structure, promise of way be according to the dissimilarity of the anti earthquake grade to all beams, pillars, wall etc. the adoption is opposite to bend in the anti of different super go together with coefficient. The basic request that the anti earthquake anti shear is before the beam carry plastic hinge that big epicenter need turn to move and don39。t need to be carry on to go together with hoop plicatedly at this time, because of adopt such coefficient can promise a swing joint very explicit. But is exactly because this kind of design method pursues the ideal beam swing joint anization to cause the first floor post pare weaker, the possibility for throng will be a swing joint, the plasticity that correspond and then have to adopt the structure measure to promise this part transforms function. In the meantime, such as if the first floor the influence of the swing joint upon the structure will pare greatly, once pressing and mating because structural whole tumble down, this has to be given guarantee up from the structure, increasing a structure of difficulty. Another project includes total body, Chinese etc. in the United States, Europe, this kind of project leading structure pillar swing joint the night appears in the beam swing joint, unlimited make the emergence of the swing joint in the meantime, but request structure and do not bee the layer side to move structure, at this time to post of super go together with coefficient to pare with to request New Zealand of want to be small, goes together with the project that the stirrup takes in to control to the post adoption in the meantime. BE super to go together with coefficient to really settle problem parison plications to the post adoption in fact: The beam carries the super influence for go together with for construct。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 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
