Revised Load Rating Procedures for Deteriorated Prestressed Concrete Beams

A number of precast, prestressed concrete bridges in Massachusetts (MA) have exhibited corrosion-induced deterioration over the years, so development of new rating methods that include deterioration are needed. This project seeks to accomplish the following objectives: (1) Categorize the severity of deterioration of precast, prestressed concrete bridges as it relates to their safety; (2) Develop engineering procedures to estimate the remaining capacity of deteriorated precast, prestressed concrete beams based on severity of the deterioration encountered. These procedures will be based on solid engineering principles verified by calibrated finite element analyses using laboratory testing of existing deteriorated components extracted from bridges scheduled for replacement. (3) Develop a reliable rating methodology that results in safe predictions of working capacity applicable to the range of deterioration encountered in existing precast, prestressed concrete bridges in MA.
