This course is designed to provide an introduction to dynamics Soil-Structure-Interaction (SSI) problems. The fundamental theoretical and computational aspects of Soil-Structure-Interaction are presented. 

The students are expected to carry out dynamic analysis of soil-structure system using contemporary numerical methods and computer programs.

Introduction to Soil Dynamics: dynamic behaviours of soils, soil shear modulus, damping; equivalent linear model, nonlinear models;

Wave propagation in elastic medium: Navier’s wave equation, body waves and surface waves, reflection and refraction of waves in layered media;

Dynamic response of soil: one-dimensional ground response analysis, linear analysis, transfer function for layered soil on bedrock, computer programs EDUSHAKE and ERA, nonlinear analysis, computer program NERA;

Soil structure interaction problems: sub-structure method, free-field, kinematic interaction, inertial interaction;

Numerical methods for SSI analysis: finite element method (FEM): time domain, frequency domain; boundary conditions in FEM: elementary boundaries, local boundaries and transmitting boundaries; program SASSI.

Foundation vibration: simplifed methods, impedance (dynamic stiffness) and compliance;

Application of computer programs Mathlab, SASSI, ERA, NERO, EDUSHAKE
