Shake Table Testing of Two-Span ABC Bridge w/ Steel Superstructure Tuesday, April 24, 2018

A 70-ft long, two-span model integrating six ABC connection types in a single bridge system will be tested under strong earthquakes using the biaxial shake table system at the University of Nevada, Reno.  The objective of the study is to determine combined seismic performance of connections that had been tested individually.  The details of the bridge model are shown here.

Sample photos of construction of the bridge.

More details about the model and the shake table testing protocol.


Dear Visitor:

Welcome to our website! Highlights of research projects and other activities related to accelerated bridge construction are presented in this site.  Please return to my main page ( for ABC projects that are directed by my but funded by NSF, the California Department of Transportation, and Nevada Department of Transportation. The effort is part of broader study and outreach covering all aspects of ABC.  The activities listed on this site are funded through ABC-UTC, which is being led by the Florida International University in collaboration with the University of Nevada, Reno, and Iowa State University as partners.  The primary focus of the UNR part of the work is on studies on earthquake-resistant connections, components, and systems for ABC and the related outreach and human resource development effort. 

The research team is indebted to these individuals and their affiliated companies for generously donating materials and providing advice: Christian Dahl and Joseph Morente of Headed Reinforcement Corp. (HRC), , Mike Harmon of Titan Construction Supply, Gaston Doiron of Lafarge, Bill McEleney of the National Steel Bridge Alliance, Utah Pacific Bridge and Steel and Reno Iron Works.

You are invited to use the material on this site with acknowledgement that includes statements such as “…funded by ABC-UTC and directed by M. Saiidi at the University of Nevada, Reno.” We welcome your comments.
