• Abstract:
  This research effort develops a reliability-based approach for prescribing inspection intervals for mast-arm sign support ; structures corresponding to user-specified levels of fatigue-induced fracture risk. The resulting level of risk for a ; particular structure is dependent upon its geographical location, the type of connection it contains, the orientation of its ; mast-arm relative to north and the number of years it has been in service. The results of this research effort indicate that ; implementation of state-of-the-art reliability-based assessment procedures can contribute very valuable procedures for ; assigning inspection protocols (i.e. inspection intervals) that are based upon probabilities of finding fatigue-induced ; cracking in these structures. The engineering community can use the results of this research effort to design inspection ; intervals based upon risk and thereby better align inspection needs with limited fiscal and human resources.
