The PIARC TC D.3 Bridges Technical Committee is publishing a worldwide compilation of case studies as examples for bridge owners in making critical decisions to ensure the safety of the traveling public during a bridge incident caused by damage and deterioration. This case study compilation has 28 worldwide case studies received from 15 unique countries.
These case studies provide examples of incidents where owners discovered damage or deterioration under two main circumstances. Firstly, damage or deterioration resulting over longer periods of time, and secondly damage or deterioration appearing instantaneously. "Triggers" or causes of this damage or deterioration include environmental impacts, increased live loads, deicing applications, poor detailing in the design phase, poor construction materials and specifications, severe loading events, natural disasters, impacts, construction defects or by human error. At times, this discovery of damage and deterioration may lead to a bridge closure, traffic restriction, or weight restriction. This should result in damage assessment techniques, load carrying capacity calculations, and subsequent remedial works to return the bridge into service.
The PIARC TC D.3 Bridges Technical Committee will publish a report to be presented at the world congress in Abu Dhabi in 2019 referring to this compilation. This report will provide an updated perspective on best practice damage assessment techniques used by bridge owners around the world and produce a decision process for bridge owners to use as a guide during any damage assessment.
Worldwide bridge owners can use the upcoming PIARC produced report decision making process as an important reference with respect to the current damage assessment techniques or to guide them through a bridge incident to ensure the safety of the traveling public.)
