Area of Expertise:
Bridge traffic loading; Dynamic interaction of trucks with bridges and roads/track; Damage detection and Structural Health Monitoring of bridges; Weigh-in-Motion of road vehicles
He has led two European CSA projects in the past and, on behalf of an Irish SME, currently leads the InfraRisk cooperation project in the Environment call. Prof. OBrien is former president of the International Society of Weigh-In-Motion and has won the cross-modal award in the EU Champions of Research competition, 2014.In Ireland, Prof OBrien’s work on Weigh-in-Motion has resulted in an increase in the allowable gross weight of 6-axle trucks from 44 to 46 tonnes. At European and the world level, his research on bridge traffic loading is identifying the nature of vehicles that govern the safety of bridges – these findings have made it possible to keep many bridges in these countries in service for much longer. The result is a bridge stock with a longer average bridge life, reducing the carbon footprint of bridges and reducing the demand for non-renewable materials.
At the time of start of the TRUSS project, Prof. OBrien had supervised 27 PhDs to completion, published 90 journal papers, 173 conference papers and 2 books.
