• Abstract:
  This report describes the instrumentation and data acquisition for the center hung segment in the largest ; truss bridge in Connecticut, located on the interstate system. The monitoring system was developed as a ; joint effort between researchers at the University of Connecticut and a company manufacturing wireless ; sensor technology, and it is the first of its kind. The great lengths between sensors, along with the difficulty ; of running wires over the trusses, led to the decision to use wireless sensors. Access to the underside of the ; bridge is severely limited, requiring closing of a lane whenever researchers are on the bridge. Since wireless ; sensors require batteries for power, necessitating replacement of batteries on a regular basis, researchers ; proposed use of solar panels along with rechargeable batteries for use with the sensors. The initial system ; was developed and placed on the bridge and used to collect strains and accelerations. Using what was ; learned from the initial system, changes and upgrades were made to the equipment. This included sensor ; modifications, replacement of some of the solar panels and revisions to the monitoring techniques. This ; report shows what was learned from the initial phases for this first-of-its kind monitoring system.
