摘　　要：用 Newmark-β法对某 2 4层含断层剪力墙的框 -剪结构作动力时程分析 ,计算该结构在 ElCentro波作用下的最大楼层位移和最大楼层剪力 .发现动力时程分析时结构的最大楼层位移曲线和最大楼层剪力曲线 ,均在剪力墙断层处发生明显的扭曲 .这种曲线的扭曲现象在振型分解法中非常不明显 ,故当作此结构截面设计时应持谨慎态度 .By using Newmark β method,a dynamic and time historical analysis is made on a 24 storied frame shear structure containing shear walls with fault;and a calculation is performed on the maximal floor displacement and the maximal floor shear of this structure under the action of El Centro wave.Significant distortion of all the curves of maximal floor disptacement and maximal floor shear of this structure are found to occur at the faults of sheal walls during dynamic and time historical analysis.This distortion phenomenon of curves is insignificant in using method of decomosing mode of vibration.This reminds us that we should be cautious in sectional design of this structure.
