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.
In May 2018, Dr. Vahid Shahsavari participated in the Engineering Mechanics Institute Conference (EMI2018) in Cambridge, MA. He gave a talk about probability-based assessment of a tidal turbine deployment system* exposed to harsh environmental events. The results of this study have been used to develop an operational decision-making guide for turbine operation in response to environmental demands.
*The south pier of the Memorial Bridge is instrumented by a tidal turbine deployment system.
In September 2017, Dr. Vahid Shahsavari attended the Northeast Bridge Preservation Partnership (NEBPP) annual meeting in New Brunswick, NJ. The NEBPP is one of the four reginal partnerships of the Transportation System Preservation Technical Service Program (TSP2) which serves the interests in bridge preservation. In this event, Dr. Shahsavari introduced different aspects and components of the Living Bridge Project for technical audience participated from state and provincial DOTs, local agencies, contractors, suppliers, consultants, and academia.
Graduate student researchers Ian Gagnon and Kaelin Chancey participated in the International Network on Offshore Renewable Energy (INORE) European Symposium in Co. Clare, Ireland the week of August 21, 2017. Ian presented a poster about his contributions to the Living Bridge Project over the past two years including the tidal energy resource assessment and design of the turbine deployment platform. Kaelin gave a poster presentation focused on the estuarine instrumentation installed on the turbine deployment platform. She also gave a talk about the entire tidal turbine deployment system located at the Memorial Bridge which was named the best presentation of the conference. The researchers were also able to tour many of the marine research facilities located on the west coast of Ireland and network with other early stage researchers from around the world.
From June 5-7, 2017, Professors Erin Bell and Martin Wosnik attend the NSF:PFI Grantee Workshop in Atlanta, GA. This workshop included over 600 attendees representing the grantees from the PFI: Building Innovation Capacity and the PFI: Accelerating Innovative Research programs. Professors Bell and Wosnik were able to share the accomplishments of the Living Bridge project with NSF staff and other grantees. The Living Bridge project team is planning on building on some of these connections to create future collaborations.
On July 3 2017, Professor Erin Bell presented the Living Bridge Project to the civil and environmental
engineering faculty at the University of Johannesburg-Auckland. Professor Bell was in Johannesburg to
support the First Avenue Institute Winter Engineering Camp for Girls. She hopes to develop a research
collaboration between the two universities to continue to support the outreach mission. There was
significant interest from the faculty at UJ to collaborate on multiple components of the Living Bridge
In October 2016, Maryam presented the paper “Structural Health Monitoring and Design Verification of Tidal Turbine Support Structure” in 75 the Annual Conference of American Society of Non-destructive Testing (ASNT) in Long Beach, Ca. She had a chance to introduce the Tidal Turbine project and talk about to other participants about monitoring issues and various inspection methods which are more appropriate for the Tidal Turbine Deployment system.
In March 2017, Maryam presented a paper on “Instrumentation and Structural Health Monitoring of a Vertical Lift Bridge” in 26 the Research ASNT Symposium, Jacksonville, Fl. She introduced the monitoring plan of the Memorial Bridge, the challenges, objectives and the procedure for designing the instrumentation plan and getting familiar about modern methods of monitoring the bridges. She is also the Recipient of the Annual ASNT travel grant for participating in the conference.
Master’s degree student, Ian Gagnon presented his work on the UNH Living Bridge – Tidal Energy Conversion System at the International Network on Offshore Renewable Energy (INORE) 2016 European Symposium in Paimpont France. He presented the work that he has done one the resource assessment for the tidal energy conversion system as well as the design of the turbine deployment platform. He also discussed other aspects of the project such as how the estuarine and structural health monitoring sensors will be used to increase awareness about the US’s critical energy and transportation infrastructure. During the week long conference he got to know and hear about the research of early stage marine renewable energy researchers from around the world. The conference included a technical trip to the port of San Nazaire where GE had just finished construction of one of the nacelles for the Block Island wind project, the US’s first offshore windfarm. Ian worked on a collaborative activity with three other researchers at the conference where they used Metocean Analytics by Open Ocean, a marine data intelligence platform, to site and perform a resource assessment for a theoretical combined wind and tidal energy conversion device array. Ian is looking forward to keeping in touch with all of the other researchers he met and is planning on attending the 2016 North American Symposium in Maine.
