In Oct 2018, Dr. Vahid Shahsavari presented the paper entitled “Effect of Damaged Structural Members on Performance Degradation of a Vertical Lift Truss Bridge” at the American Society for Nondestructive Testing (ASNT) Annual Conference, Houston, TX. His talk was about the effect of damaged structural members on the load carrying capacity of the Memorial Bridge. The proposed approach provides a realistic means to determine the members that are key to the overall system strength and should receive more attention by bridge owners and instrumentation engineers. This study was conducted under the direction of Professor. Erin Bell as the Principal Investigator of the Living Bridge Project. The authors acknowledge support from BDI, HNTB, and NHDOT which were instrumental in the design of the structural health monitoring system, model creation, and diagnostic load testing.
In March 2018, postdoctoral research scholar, Vahid Shahsavari, presented the paper entitled “Structural Health Monitoring of a Vertical Lift Bridge Using Vibration Data” at American Society for Nondestructive Testing (ASNT) 27th Research Symposium, Orlando, FL. He presented how statistical pattern recognition algorithms and advanced signal processing tools can be integrated to eventually develop a reliable baseline for future condition assessment of the Memorial Bridge.
In January 2018, Dr. Vahid Shahsavari gave a talk at Transportation Research Board (TRB) Structural Health Monitoring Subcommittee in Washington, DC. His talk was focused on long-term monitoring of bridges under operational and environmental variations.
