Peer Review
The BTC method for Cable Strength Evaluation was subject to independent peer review by different suspension bridge owners:
MTA Bridges & Tunnels, New York City
New York State Department of Transportation
New York State Bridge Authority.
Endorsement of the BTC Method by Engineering Reliability Experts:
"You have provided a good rationale for the sampling of the wires in the suspension cables. Your suggestion is reasonable and it deserves to be implemented. It will serve not only as a method for this particular instance, but it will serve as a template for other investigations."
Prof. Theodore Galambos, University of Minnesota, Member of the National Academy of Engineering, December 2007
Patent for BTC Method for Cable Strength Evaluation


The BTC Method obtained a U.S. Patent.

The BTC Method is a comprehensive, probabilistic proprietary state-of-the-art, patented methodology that employs random sampling, principles of fracture mechanics, and statistical analysis for strength evaluation of bridge cables. The BTC Method provides accurate assessment of the proportions of broken and cracked wires, and forecasts service life of the bridge cable using degradation kinetics; thus providing invaluable information to owners regarding budgeting and future inspections.


Recent Applications of the BTC Method:
The BTC Method was recently applied for the evaluation of the remaining cable strength at the Bronx-Whitestone Bridge and the Mid-Hudson Bridge.
