A direct approach of coupling the element-free Galerkin method (EFGM) to both the finite element method (FEM) and the boundary element method (BEM) is applied to study dynamic soil-structure interactions. The structure and the soil body are assumed to be two-dimensional systems and discretized by EFG nodes, while the boundary of the soil region is modeled either by FEM or BEM to impose the boundary conditions in an easy way. Essential parameters in the EFG domain are chosen in a way where stable and reliable results at a relatively low cost are obtained. The accuracy and efficiency of the two new methodologies are compared to those of the conventional mesh-based approaches. [ABSTRACT FROM AUTHOR] |
