• Abstract:
  This research project used wireless smart sensors to develop a cost-effective and practical portable structural health monitoring ; system for railroad bridges in North America. The system is designed for periodic deployment rather than as a permanent ; installation to enable campaign-style bridge response monitoring under in-service conditions. This research project measured ; bridge responses from a 310 feet long steel truss bridge using wireless sensors and developed a finite element (FE) model to ; obtain global bridge responses under varied train loads and speeds. Additionally, this project developed a new simple beam model ; that predicts critical speeds and resonances based on train traffic properties. The results from this pilot project provide a ; technological foundation to develop campaign monitoring sensor technology as an important tool with which to manage railroad ; bridge assets.
