Abstract:

To establish a site-specific database for bridge evaluation and future bridge design, DOTD established a long-term health monitoring system at the I-10 Twin Span Bridge. The bridge is instrumented from deck to piles to capture bridge response (both substructure and superstructure) to live loads. The purpose of this instrumentation is to perform structural health monitoring (SHM) of the bridge during normal traffic events as well as during extreme events, overloads, wave surges, or ship collision. This study is to provide field data-based support to DOTD to fully implement the SHM and determine the effects of traffic loads on instrumented components of the structure. In addition to instrumentations for structural response such as strains, an OSMOS weigh-in motion (WIM) scale has been installed adjacent to pier M19 to collect live load information.
