Simplified Analysis of Layered Soil-Structure Interaction

Review of static soil-framed structure interaction

“…Extensive studies were carried out to modify this solution since it is dependent of a coefficient called sub-grade modulus which brings uncertainty into the calculation since this parameter does not represent any characteristic of the soil, Stavridis (2002). Sub-grade modulus of reaction as a key factor of Winkler hypothesis has been focused in order to be more accurately interpreted through a mathematical model namely Winkler-Type Simplified Continuum (WTSC), Horvath (1983a).…”

Rigid Foundations Resting on an Elastic Layered Soil

“…The deformational behavior of the soil is determined using a discretization of the soil surface and not of the soil mass itself. This is achieved by applying an explicit analysis using as input the thickness, the compression modulus and the Poisson's ratio of each layer (Stavridis 2002). The latter lies practically between 0.3 for noncohesive and 0.4 for cohesive soils and its practical influence on the results is of rather minor importance.…”

Elastoplastic medium for foundation settlements and monotonic soil–structure interaction under combined loadings

“…The studies by Lee and Harrison [1], Hays and Matlock [2], Vaish and Chopra [3], and Miyahara and Ergatoudis [4] are examples of early work, where analytical or computational methods were implemented to examine the interactions between the superstructure and the foundation soil under both static and dynamic loads. The works by Allam et al [5], Novak and Henderson [6], Ciampoli and Pinto [7], Stewart et al [8,9], Halabian and El Naggar [10], and Stavridis [11], are examples of how the early methods gradually evolved. The very large number of publications on this subject, the listing of which is beyond the scope of this paper, indicates clearly that the subject of soil-structure interaction was and continues to be a subject of great interest.…”
