Abstract

This study applies the Integral Transform Method (ITM) to solve the problems caused by dynamic loads that work on structures and its interactions with the soil. The structure and part of the soil from the half space layer are modeled with Finite Elements (FEM) where at the boundary must be coupled with the dynamic stiffness matrix from the half space calculating used Integral Transform. To obtain the dynamic stiffness matrix of the half space, the wave equation in the elastic half space which is a coupled partial differential equations must be uncoupled first with Helmholtz's potential then it is used integral transform to find the wave equation in the transform domain. To get a response to the original domain, reverse transformation is performed using Inverse Integral Transform. This method is known as ITM - FEM Coupling.
