Seismic Performance of Precast Bridge Columns
with Grouted Couplers

Dear Visitor:

Welcome to our website!  Highlights of a research project on the performance of grouted coupler connections under seismic loading are presented.  The study is funded by Caltrans through grant No. 65A0425.  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. Saad El-Azazy and Dr. Charles Sikorsky, the Caltrans Research Program Managers for their support and advice.  The interest and comments of Mr. Mike Keever, Mark Mahan and Ron Bromenschenkel are also much appreciated.  

The research team is indebted to Mr. Toshi Yamanishi and Jim Schroder of Splice-Sleeve North America for generously donating materials and providing advice in the course of this project.

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.
