• Abstract:
  Non-destructive strain monitoring has been used for two decades on Connecticut’s bridges to ; supplement visual field inspections. These studies have addressed a wide range of problems, ; including fatigue cracking in diaphragm connections, cracked secondary connections, main girder ; cracking, load ratings, over-load conditions, and concerns with movable bridges involving drive ; mechanisms and counter-weight supports. Monitoring has often shown that repairs are not necessary, ; and when necessary, the data collected in the monitoring has been used to provide information on how ; best to design the repair. The benefit from the monitoring program during the past two decades has ; saved the State of Connecticut millions of dollars, well below the cost of implementing the monitoring ; program.
