Mutual interaction among three nearby shallow foundations
Mutual interaction among three nearby shallow foundations
In dense urban areas, an interaction among closely-spaced buildings could arise through the underlying soil even if the buildings are structurally disconnected. In seismic design of new buildings or safety assessment of existing ones, the structure-soil-structure interaction is completely disregarded and each building is analysed independently of its neighbours. To understand if this practice represents a gross simplification of reality, the paper illustrates a parametric study in which the mutual interaction among three rectangular shallow foundations on an elastic halfspace has been investigated through a continuum-based approach with the FLAC3D software. The objective of the study is to evaluate how the different terms of the soil-foundation impedance matrix could be affected by the presence of nearby structures in dependence of the foundation-foundation spacing.
