Research Report No. FHWA-ICT-13-002 Experimental Investigation of the Seismic Response of Bridge Bearings is now published and available online.  The report, which is authored by J. LaFave, L. Fahnestock, D. Foutch, J. Steelman, J. Revell, E. Filipov and J. Hajjar, describes an extensive full-scale bearing testing program that was conducted as part of the project Calibration and Refinement of Illinois’ Earthquake Resisting System Bridge Design Methodology.

In addition, a subset of this bearing testing program is reported in the July 2013 issue of the ASCE Journal of Bridge Engineering:
