Condition Assessment of Corroded Prestressed Concrete Bridge Girders (C3.2018)

The problem the research team is trying to solve is the condition assessment of corroded prestressed concrete (PC) bridge girders in New England. The problem is important because that PC bridge girders are a critical component of highway bridges. Concrete spalling and prestressing strand corrosion not only cause losses in prestress but also lead to premature failures of PC bridges. The team proposes to (1) conduct multiphysical field inspection (using 3D photogrammetry, radar, impact-echo, and ultrasound) and to (2) develop an integrated assessment framework for predicting the level of structural damage and prestress losses for PC bridge girders. This project will enhance the transportation infrastructure durability as follows: (1) Efficient condition assessment algorithm – The chemical-mechanical model proposed by this research will provide a theoretical, but computationally efficient algorithm for assessing the remaining structural strength of PC bridge girders. (2) Data-driven decision-making – The vulnerability function for defining multiple damage states adopts the Bayesian framework, a data-driven method. The outcome can be customized improve the durability of PC bridges through effective structural repair.
