Abstract
This article presents a numerical model and case study of the dynamic response of piled foundation blocks. The problem consists of blocks with three different geometries, which are supported by groups of two, three and four piles. Horizontal and vertical time-harmonic loads are applied to the blocks, and their horizontal and vertical responses are computed via a coupled method. The method consists in using finite element discretizations to model the blocks, and the impedance matrix method to model the embedded pile group. Coupling between the two domains is obtained by imposing continuity and equilibrium conditions between pile heads and the discrete nodes of the blocks. The analysis considers the influence of pile length and distance in the response of the system. The results show that, depending on the loading direction, these parameters may have a significant effect on the response of the system, and that pile-to-pile interaction must be modeled properly.
