Redundancy Analysis of Fort Pierre South Dakota Bridges

In this webinar, S-BRITE Director Rob Connor discusses the proposed project of a full-scale fracture simulation test on the Fort Pierre Bridge in South Dakota to obtain benchmarking data for FC plate girder systems.

Probability of Detection (POD) Study for Bridge Inspection Related to Steel Bridges

To determine the current performance of inspectors with the industry's present standards of training, a comprehensive Probability of Detection (POD) study is underway to determine the likelihood of inspectors finding cracks, surface corrosion and weld defects of various sizes on a bridge structure. This study will test multiple inspectors’ abilities to identify different defects under various environmental conditions on a bridge structure. The study will provide state transportation agencies, as well as private inspection agencies, invaluable information regarding typical inspector performance. The outcomes will be used to establish procedures to improve inspection reliability, and develop inspector performance-based certification criteria and procedures.

Member-level Redundancy in Built-up Steel Members

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.
