Reliability-based life cycle assessment management of bridges
This project aims to evaluate life-cycle structural performance of bridges. Bridges require significant maintenance and rehabilitation; however road authorities currently face numerous challenges in maintaining road assets due to inexact and incomplete information resulting from uncertainty of future traffic demand and degradation of construction materials. By developing an integrated approach involving reliability-based computational methods and modern non-destructive assessment techniques, this project will allow the accurate prediction of ongoing damage through uncertainty analysis. The model developed will provide significant benefits to both the economy and society by ensuring the longevity and safety of the road structures.
