Dynamic Interaction of Inclusion‐Soil‐Foundation System

Abstract

The effects of an inclusion on the dynamic response of a shear wall foundation system subjected to plane harmonic SH‐waves are investigated. The inclusion and foundation are modeled as having circular and semicircular cross sections, respectively. A closed form solution for the inclusion‐soil‐foundation interaction problem is obtained by the method of wave functions expansion. The image technique is employed to account for the reflection of waves at the ground surface. The numerical studies carried out indicate that the response of the foundation and the shear wall are influenced by both the size and location of the inclusion, especially in the low frequency range. On the contrary, for any inclusion location, the direction of excitation has greater influence on the response of the system at higher frequencies. It is also observed that the effect of the inclusion on the system response decreases with an increase in the mass of the shear wall.
