摘　　要：目前生态复合墙结构体系采用的"两阶段三水准"抗震设计方法已无法满足业主对建筑结构性能目标的个性化要求。将结构特有的三道抗震防线与基于性能的抗震设计理论框架相结合,分别以三道抗震防线的屈服位移值对结构的性能水准进行量化。以倒三角形水平分布荷载等截面剪切型悬臂柱的侧移曲线作为结构的初始侧移模式,结合位移反应谱提出其基于位移设计的具体步骤,并对实例进行了三个性能目标下的设计计算。算例表明:提出的多层生态复合墙结构基于位移的抗震设计方法能够针对不同性能水平进行设计计算,简单实用。Now the “two-phase and three-level” seismic design method , which has been used in the calculation of ecological composite-wall structure system , has failed to meet the modern owner ’ s personalized requirement of building structure performance target .Combining three special seismic defence lines of ecological composite-wall structure with the theoretical framework of seismic design based on performance , and based on yield displacement value of the three seismic defence lines , the performance level of structure was quantified .Applying the inverted triangular distribution of lateral force to the cantilever column of constant section , and the displaced shape of the column was regarded as the initial mode of lateral displacement;combining with the displacement response spectrum , the specific steps of the displacement-based design method were put forward and three performance targets design of a example were calculated .Example shows that the proposed multiple ecological composite wall structure displacement -based seismic design method is simple and practical , which can be designed and calculated according to different performance levels .
