Performance Based Seismic Design of Innovative Damage Free Rocking Steel Bridge Piers
The objective of this research is to investigate, through experimental and numerical studies, the concept of self-centering mechanism in steel bridge piers. Since any damage to a transportation system could have significant impacts on society and economy, the need for the design and development of new bridge components and systems with damage avoidance mechanisms has been increasingly highlighted over the recent years. The use of steel rocking bridge piers, where energy dissipating elements can be easily removed after an earthquake, can significantly reduce construction time and expenses, seismic damages and corresponding economic losses. However, currently there is no proper guideline for designing such piers. This research will examine the various damage states and performance of steel rocking bridge piers to eventually develop performance-based design guidelines for inclusion in the Canadian Highway Bridge Design Code (CSA S6).
