Out-of-plane soil-structure interaction: A tapered shear wall on flexible semi-circular foundation excited by plane SH waves

Abstract

Although most analytical research on soil-structure interaction (SSI) has assumed a rigid building foundation, numerical and experimental studies have shown that the dynamic response of a structure supported on flexible foundation will differ significantly from the same response on a rigid foundation. The analytical solutions have provided physical insights into the nature of the SSI problems and offered benchmarks to verify the approximate and numerical methods, among others. To this end, in this paper, we present an analytical solution of a tapered shear beam on an elastic semi-circular foundation excited by incident plane SH waves.
