摘　　要：以B市D区的实际工程项目为例,制定对应的地震设防目标对结构的抗震性能进行分析,并应用EPDA&PUSH软件分析该工程项目的静力弹塑性,对设防地震作用下中震弹性与中震不屈服性能进行对比,通过EPDA对中震弹性与中震不屈服两种性能目标进行综合分析。结果表明,结构薄弱层在中震弹性设防目标下的层数是14~17层,结构薄弱层在中震不屈服设防目标下的层数是15层;对最大有害层间位移角,中震弹性具有较小的结构变形。通过研究得出结论,中震弹性要优于中震不屈服,对于构件要求为强剪弱弯的建筑,抗弯应选择中震不屈服,抗剪应选择中震弹性。Taking the actual engineering project in District D of City B as an example, the corresponding seismic fortification target is formulated, and the seismic performance of the structure is analyzed, and then the static elastoplasticity of the project is analyzed by using EPDA & PUSH software.The moderate earthquake elasticity and the moderate earthquake non-yielding performance were compared, and the two performance targets of the moderate earthquake elasticity and the moderate earthquake non-yielding performance were comprehensively analyzed through EPDA.The results show that the number of structurally weak layers under the moderate earthquake elastic fortification target is 14~17,and the number of structurally weak layers under the moderate earthquake non-yielding fortification target is 15 layers.For the maximum harmful interlayer displacement angle, the moderate earthquake Elasticity has less structural deformation.Through research, it is concluded that the elasticity of moderate earthquakes is better than that of non-yielding.For buildings requiring strong shear and weak bending, the bending resistance should be selected for moderate earthquake non-yielding, and the shear resistance should be selected for moderate earthquake elasticity.
