The main purpose of seismic analysis is to give engineers the necessary tools to estimate forces that can be applied to bridges and to understand how they respond to earthquake ground motion. This course provides the concepts of modelling of bridges for linear and non linear seismic analyses and emphasizes on the important factors that control their seismic response such as effective weight, stiffness, damping etc... The application of modelling for seismic analysis of bridge structures is illustrated through practical examples of bridges with different geometry and configuration.
