- The objective of this research is to quantify the redundancy possessed by built-up steel members (bolted or riveted). Typically, built-up members will not 'fail' if one of the components fails (whether through fatigue or fracture). However, there is very little experimental data quantifying the remaining fatigue life and strength of a member in which one of the components has failed.

The objective of this research is to quantify the redundancy possessed by built-up steel members (bolted or riveted). Typically, built-up members will not 'fail' if one of the components fails (whether through fatigue or fracture). However, there is very little experimental data quantifying the remaining fatigue life and strength of a member in which one of the components has failed.
Furthermore, if built-up members are located in bridges classified as fracture critical, evidence of sufficient member redundancy may allow the bridge to be reclassified as non-fracture critical. Reclassification would release these members from the more rigorous arms-length inspection currently required. More rational inspection intervals for these members will then be permissible. These intervals will be addressed through the outcomes of this research.
