Influence of analysis models and damping method to nonlinear earthquake response of complex bridges

From previous studies of damaged bridges, it is known that the use of non-linear dynamic analysis is important for estimating the safety of bridges. Already much effort has been put into studying the earthquake response of bridges not only of their non-linear behaviour but also on the selection of the analysis models. This paper describes and discusses a study of the influence of the analysis models and damping method used to assess the non-linear earthquake response of complex bridges. A comparative analysis of three different analysis models and damping methods is carried out on a complex continuous bridge, and the paper provides an example of the earthquake analysis of such a bridge.
