Abstract :
Bridges, as an essential part of transportation system, play a special role in economy, politic and military all around the world. Serviceability of
bridges is of high importance especially in emergencies, helping injured people and proportioning transportation after earthquakes. Earthquake
regulation codes, normally suggest linear methods to conduct the analysis, and nonlinear analysis is barely used by practicing engineers. In
this paper, we analyze a typical concrete bridge located in Iran and use both nonlinear dynamic and static procedures at two hazard levels.
This study compares both methodologies, analyze the results and presents some recommendations to reduce the seismic vulnerability.
