TL;DR: In this article, the response of wind turbines founded on suction caissons and subjected to lateral monotonic, cyclic and earthquake loading is studied with due consideration of the role of soil-sidewall adhesion, using non-linear three-dimensional finite-element analyses.
Abstract: The response of wind turbines founded on suction caissons and subjected to lateral monotonic, cyclic and earthquake loading is studied with due consideration of the role of soil–sidewall adhesion, using non-linear three-dimensional finite-element analyses. In the case of monotonic and slow cyclic lateral loading it is shown that imperfect interface bonding could reduce the moment capacity and may lead to foundation detachment or even uplifting in the case of shallowly embedded caissons. A preliminary comparison of two caisson alternatives has shown that increasing the caisson diameter while maintaining the embedment ratio is more efficient in terms of material resources than increasing the skirt length while keeping the diameter constant. The second part of the study evaluates the response of a soil–foundation–wind turbine interacting system subjected to earthquake shaking. Contrary to an often prevailing impression that seismic effects are insignificant, apparently originating from evaluating the seismic...

TL;DR: In this article, the influence of dynamic soil-structure interaction (SSI) on the behavior of seismically isolated cable-stayed bridge supported on a rigidly capped vertical pile groups, which pass through moderately deep, layered soil overlying rigid bedrock is assessed.

TL;DR: In this article, a set of simple numerical models have been developed to describe how soil-structure interaction can be influenced by soil variability, including a description of the soil spatial variability, within the frame of geostatistics, where the correlation length of soil properties is the main parameter.
Abstract: The longitudinal variation of soil properties has a major influence for many types of structure, including pavements, buried pipes, raft foundations and railways, as it induces stresses and/or displacements that cannot be predicted when assuming soil homogeneity. A set of simple numerical models has been developed to describe how soil–structure interaction can be influenced by soil variability. These models include: (a) a description of the soil spatial variability, within the frame of geostatistics, where the correlation length of soil properties is the main parameter; and (b) a mechanical description of the soil–structure interaction, which depends on the structure resting on the ground. There are some differences between a (more or less) rigid raft on piles, a set of buried pipes with (more or less) flexible connections and a hyperstatic beam, but the basic principles of mechanics are similar in all these cases. Several very general conclusion are drawn. (a) Soil heterogeneity induces effects (differen...

TL;DR: In this paper, a seven-storey hotel building in Van Nuys, California has been measured by strong motion accelerographs and its aftershocks, including the 1971 San Fernando (ML=6.6, R=22), 1987 Whittier-Narrows (ML =5.9, R =41, km), 1992 Landers (ML 7.5, r=186, km) and 1994 Northridge (ML 6.4, r = 1.5 km) earthquakes.
