Abstract

Engineering, Civil Science & Technology Engineering Technology
The Tacony-Palmyra Bridge steel tied arch span is currently being evaluated through a new approach termed Temperature-Based Structural Identification (TBSI). TBSI uses temperature as the forcing function for long-span bridge evaluation. Most bridge structures experience significant daily and seasonal temperature variations thus causing relatively large strains and displacements. As a result, TBSI takes advantage of this for long-span bridge assessment. The Tacony-Palmyra Bridge arch span has been instrumented for measurement of local temperatures (input) along with local strains and global displacements (output response). The objectives of the evaluation include (1) finite element model calibration for refined structural ratings, (2) evaluation of long-term performance criteria, and (3) development of automated alert criteria for a real-time structural health monitoring (SHM) system. The results of the project provide the bridge owner with reliable information to better manage the structure.
