Since the construction of modern structures, civil engineers have been assisting infrastructure owners with planning, designing, constructing and inspection of their assets using the methodologies that have been developed empirically. Most of these heuristic approaches are based on simplified assumptions. As the infrastructure, especially the bridge inventory, continues to age and becomes a more complicated system its behavior changes. In these cases the traditional methodologies provide a significant challenge to bridge engineers, especially during inspection, load rating and overall safety assessment of “geriatric” bridges. Even though, in some cases the current conventional approaches have met the needs of the owners, there are an increasing number of situations where they have been proved insufficient. In recent years, engineers and bridge owners have started to hire smart technologies and sensing techniques in planning, evaluation, and monitoring of their assets which are mostly geriatric signature bridges that cannot be replaced or their replacement requires a few years during which the bridge has to remain in safe service. This presentation will discuss risks associated with infrastructure, when should we use technology in decision-making, and real-world examples, including short-span bridges, medium-span bridges, and long-span bridges.
Presenter: Ehsan Minaie, PhD, PE
Dr. Minaie has been actively involved in analysis, design, and rehabilitation projects as a structural engineer and is registered as professional engineer in the states of California, Maryland, New York, Virginia and Washington DC. He is a research engineer for Pennoni’s Intelligent Infrastructure Systems (IIS) Division, which is responsible for structural evaluation, monitoring and testing of bridges and integrates Pennoni’s bridge design, bridge inspection and structural evaluation expertise into a value added service for bridge owners and asset managers. His expertise also includes structural identification of aging bridges using novel technologies for preservation purposes. He is also a FHWA/NHI certified bridge inspector and has worked on numerous domestic and international projects. Ehsan serves on the ASCE/SEI “Bridge Management, Inspection & Rehabilitation Committee” of the Technical Administrative Committee on Bridges as well as TRB Structural Health Monitoring Committee. Dr. Minaie received his PhD from Drexel University where he is currently an adjunct professor in the Civil, Architectural and Environmental Engineering Department. In addition, Ehsan has many publications in international journals, and is a reviewer for the Journal of Structural Engineering of ASCE and Earthquake Spectra Journal.
