Abstract:What if every time a bridge on a lonely road got icy, it automatically notified the local DOT to begin ice-control safety measures? What if a bridge could tell someone
every time an overloaded truck hit the decking, or when the trusses under it began to weaken? This project, a partnership of Washington State University, the University
of Alaska Fairbanks, and Kansas Structural Composites, Inc. takes the first steps to develop, manufacture, test, and implement Smart Honeycomb Fiber-Reinforced
Polymer (S-FRP) sandwich materials for transportation projects. This material integrates advanced composite materials with sensors and actuators. So far, researchers
have tested an S-FRP sandwich deck panel, evaluated several S-FRP sandwich beams in cold temperatures, and developed effective structural-health monitoring
strategies. Dynamic tests of the S-FRP sandwich deck panel with and without damage continue, and structural-health monitoring strategies for cold temperature exposures
will be developed. A combined experimental, theoretical, and numerical approach will result in new techniques for structural-health monitoring and damage identification
of thick sandwich deck panels. It is anticipated that, with wireless communication technologies, the developed structural-health monitoring strategies will be capable of
remotely monitoring and assessing the structural integrity of sandwich bridge decks in cold regions.
