Residual Displacement Control of ABC Columns with Iron-Based SMA Recentering Mechanism under Seismic Loads



Dear Visitor:

Welcome to our website!  Highlights of a research project on the seismic performance of precast bridge columns with iron-based shape memory alloy (Fe-SMA) bars for recentering and with ABC socket connections are presented on this site.  The study is funded by Caltrans through grant number No. 65A0589.  However, the material and opinions presented on this site are those of the authors and do not necessarily represent the views of Caltrans. Special thanks are due Dr. Issam Noureddine, the Caltrans Research Program Manager, for his support and advice.  Dr. Mark Mahan of Caltrans is thanked for all his helpful comments, feedback, and interest in different aspects of the project.  Gratitude is due to Dr. Moslem Shahverdi and Dr. Masoud Motavalli of Empa, Switzerland for providing extensive information and feedback about Fe-SMA and Dr. Julien Michels of re-fer AG of Seewen, Switzerland for providing invaluable information.  Ref-fer AG ofSeewen is thanked for its timely and generous donation of Fe-SMA bars. 
Please feel free to use the material with acknowledgement that includes statements such as “…funded by Caltrans and directed by M. Saiidi at the University of Nevada, Reno.”  We welcome your comments about this site.
