The dynamic soil-structure interaction of a shear wall embedded in elastic isotropic and homogeneous soil layers underlain by bedrock, subjected to SH waves, is modeled in the present article. The soil layers consist of irregular interfaces and it has been shown that the scattering due to the roughness of the layers has significant effect on the displacement of both the foundation and the shear wall. To demonstrate the phenomena indirect boundary element method (IBEM) has been used on the basis of its validation in previous problems of similar type. The system response is compared with the analytical solution of the same type of model for vertically propagating incident SH waves. It is observed that for the low frequency of wave, displacement is abruptly high, and as a result the combination of shear wall and foundation perceives resonance. The thickness of the soil layer, mass of the shear wall, stiffness of the bedrock and the soil layers all affects the system frequency and displacement.

SH波散射对剪力墙与土层动力相互作用的影响

本文模拟了埋入基岩下均质弹性均质土层中的剪力墙在SH波作用下的动态土-结构相互作用。土层由不规则的界面组成，并且已经表明，由于土层的粗糙度而引起的散射对地基和剪力墙的位移都有显着影响。为了证明这种现象，间接边界元方法（IBEM）已经在类似类型的先前问题的验证基础上使用。将系统响应与用于垂直传播入射SH波的相同类型模型的解析解进行比较。可以看出，对于低频率的波浪，位移突然变高，结果，剪力墙和地基的组合会产生共振。
