摘　　要：针对某异型框架-抗震墙结构的薄弱部位易失效引起结构抗震性能的急剧退化,导致整体失效的问题,论文分析了各类构件对整体参数的影响,通过时程分析法进行了地震作用下的响应分析,并应用正交试验法进行了参数研究。结果表明:抗震墙高厚比是影响该类型结构整体刚度的第一要素,工程设计过程中当此类结构外围变楼层截面积部分的构件抗震性能不满足要求时,可通过加厚内部的抗震墙、增大内部抗震墙部分的刚度来优化整体结构布置。Aiming at the problem that the weak part of a special-shaped frame-aseismic wall structure is easy to fail,which leads to the rapid degradation of the seismic performance of the structure and the overall failure,this paper analyzes the influence of various components on the overall parameters,analyzes the response analysis under the earthquake by using the time history analysis method,and conducts the parameter research by using the orthogonal test method.The results show that the ratio ofheight to thickness of aseismatic wall is the first factor that affects the overall stiffness of this type of structure.When the aseismatic performance of the component of the outer part of this type of structure with variable floor cross-sectional area does not meet the requirements in the engineering design process,the overall structure layout can be optimized by thickening the internal aseismatic wall and increasing the stiffness ofthe internal aseismatic wall.
