Kinematic framework for evaluating seismic earth pressures on retaining walls
TL;DR: In this article, the authors demonstrate that the kinematic component of interaction varies strongly with the ratio of wavelength to wall height (λ/H), asymptotically approaching zero for large λ/H, and oscillating between the peak value and zero for λ /H < 2.3.

Combined loading of caisson foundations in cohesive soil: Finite element versus Winkler modeling
TL;DR: In this paper, the undrained response of massive caisson foundations to combined horizontal, vertical and moment loading is parametrically investigated through a series of 3D finite element analyses, and the results are then used as a feedback for calibrating the parameters of a generalized four-type spring model, originally proposed by Gerolymos and Gazetas (2006), through a genetic algorithm-based optimization procedure.

Analysis of machine foundation vibrations: State of the art
TL;DR: A review of the state-of-the-art of analyzing the dynamic response of foundations subjected to machine-type loadings can be found in this article, where the authors present simple formulae and dimensionless graphs for both the static and dynamic parts of impedances, pertaining to surface and embedded foundations having circular, strip, rectangular or arbitrary plan shape and supported by three types of idealized soil profiles: the halfspace, the stratum-over-bedrock and the layerover-halfspace.
