In this study, new and integrated Smart honeycomb Fiber-Reinforced Polymer (S-FRP)

sandwich materials for various transportation construction applications, with particular emphasis

on highway bridge decks in cold regions, were developed and tested. The novelty integrates

advanced polymer composite materials with smart piezoelectric sensors and actuators to form

smart structures, and along with advanced material technologies and proposed damage

identification algorithms, it is capable of improving construction speed in cold climates and selfmonitoring

structural conditions in remote sites. A combined experimental and analytical study

to develop, evaluate and test the S-FRP sandwich materials was conducted, and related studies

on dynamic response, temperature effect and scale-up of test results, development of viable and

effective damage identification algorithms and techniques more suitable for 2-D plate-type

structures, and experimental characterization were investigated.
