چکیده:

Soil-structure interaction refers to the interaction between a structure, its foundation and the subsoil. As the term soil-structure interaction covers a broad field, the work presented in this paper will berestricted to the analysis of raft or piled-raft foundations under static load. Piled-raft is compositestructures which are comprised of three elements: the piles, raft and supporting soil. Loads applied to the raft are transferred to the soil through the piles. Therefore, it is necessary to take into account theinteraction among the three elements. Four different types of interaction have to be considered in the analysis. In this paper, the interaction mechanism for piled-raft foundations is discussed and the use of the finite layer technique to compute the interaction factors is presented
