Research Project Summary Information

Fiber Reinforced Plastic for Bridge Repair(ST6643-1)

Research Foundation of The City


This project addresses the ongoing need for information regarding long-term performance of Fiber Reinforced Polymer (FRP) composites in bridge repair applications. The degradation of the properties of the FRP, primarily strength and stiffness, and the load transferability of the epoxy resulting from environmental conditions will be investigated.

Project Description

A systematic laboratory investigation will be undertaken to evaluate the mechanical response of typical FRP composites and adhesives used in bridge applications. A mechanistic model to predict the behavior of FRP reinforced concrete members will be developed based on the experimental test results. The predictive model will be validated through results of tests on small-scale FRP reinforced composite beams. Additional validation of the laboratory test results and the degradation models is planned to be performed in a later phase of the project, in collaboration with NYSDOT, by comparison with data collected in the field. The final product of this project will be a computer program provided on a CD-ROM. The program will be provided to NYSDOT personnel for testing and evaluation. The CUNY Office for Technology Transfer will coordinate the marketing of the product to structural engineers interested in using FRP technology for repairing deteriorated bridge members.


Benefits include reduction in traffic congestion and delays due to FRP use in bridge repairs; quantification of decreased fuel consumption based on maintained traffic flow; quantification of decreased tailpipe emissions associated with fuel savings; and economic savings available to the State of New York via FRP use.

Project Results

Very competent research was conducted and well documented. The understanding of the environmental issues was increased, but the commercial aspect of the software product was never realized.
