Description
The near field of Soil and the Structure was modeled with FEM, while to model the far field of the soil, SBFEM was used. A Fortran90/95 program was written and for Numerical Methods such as Runge-Kutta Method, Solution of Linear Equations, different sub-routines from sources like LAPACK were used. SBFEM was suitable for this purpose as it can model the semi-infinite soil accurately, without which there will be (spurious) wave reflections from Artificial-Boundary (which is often used in FEM only models). Also, unlike BEM, SBFEM does not require any fundamental solution. I studied various dynamical charachteristics of a vibrating structure, by varying different geometrical and soil parameters. Also the accuracy of this model was investigated by comparing with various benchmark results available in Literature.
