Out-of-plane (SH) soil-structure interaction: Semi-circular rigid foundation revisited
Abstract The model studied in this paper presents an extension of previous work for a shear wall on a semi-circular rigid foundation in an isotropic homogeneous and elastic half-space. The objective is to develop a soil-structure interaction model that can later be applied to the case of a flexible foundation. As shown in the Introduction below, Luco considered the case of a rigid foundation subjected to vertical incident plane SH waves, and Trifunac extended the solution for the same rigid foundation subjected to SH waves but for arbitrary angles of the incidence. In this paper, a new approach and model are presented for the same semi-circular rigid foundation with a tapered-shape (instead of rectangular) superstructure. The analytical expression for the deformation of the semi-circular rigid foundation below this tapered shear wall with soil-structure interaction in an isotropic homogeneous and elastic half-space is thus derived. Results are then compared with those of Trifunac discussed in the section below. This problem formulation can and will later be extended in the case of a flexible foundation that is semi-circular or arbitrarily shaped.
Highlights Soil-structure interaction (SSI) remains an important current research area. Proposes a new analytic solution method, one that agrees with Trifunac [2]. Analytic solution for tapered-shape structure. No analytical solution up-till-now exists for flexible elastic foundation Propose. Proposed method can be extended to flexible foundation and in-plane P, SV waves.
