Abstract
Numerical models of pile groups are a fundamental component of many dynamic soil-structure interaction analyses. Most works consider a small number of piles and soil layers, which is justifiable for ordinary applications. This paper deals with computational issues that arise when extraordinarily large-scale pile groups are considered. A general implementation for dynamic analysis of large-scale pile groups embedded in a viscoelastic layered soil under external loading is presented. Beam equations are used for modeling the piles, whereas Green’s functions for layered media are applied to represent the soil. Modern computing tools crafted into the present implementation enable not only massively large pile groups to be modeled, but a nearly arbitrary number of soil layers and excitation frequencies to be considered, which extend the modeling capabilities of the formulation considerably.
