The soil-foundation interaction is one of the most important issues in geotechnical engineering that deals with studying the soil behavior subjected to the side loading. Winkler’s model is the first and simplest method for consideration of the soil-foundation interaction. It is vitally important to determine the coefficient of subgrade reaction of the soil. Since several methods have been prov...

In this paper, the influence of soil-structure interaction (SSI) on a torsionally coupled turbo-generator (TG) machine foundation is studied under earthquake ground motions. The beneficial effects base isolators in TG motions are also duly, considering SSI. A typical analyzed using three-dimensional finite element (FE) model. Two superstructure eccentricity ratios considered to represent torsio...

It is hypothesized that interplay of earthquake, soil, foundation and structure (SFS) dynamic characteristic, and their interaction in time domain, control the behavior of SFS system during earthquakes. Moreover, (passive and active) control of spatial and temporal location of seismic energy dissipation (preferably in soil) can improve safety and economy of SFS systems. Such energy dissipation ...

Information on the influence of impregnation of cementitious slurry at the soil-structure interface of bored cast in-situ foundation is inadequate in available literatures. Moreover, influence of such impregnation on negating the detrimental effects of smear zone, formed by construction tools, surrounding the borehole is also unknown. In classical foundation engineering, influences of smear and...
