Reliability‐based smart bridge management

How can bridges be inspected and monitored more efficiently?

Using reliability- and risk-informed methods, the effect of inspections and monitoring is quantified. This enables to plan the optimal extent and scheduling of inspections on bridges. It furthermore ensures the optimal use of information obtained from monitoring systems. Through case-studies on RC bridges subjected to corrosion and of steel bridges subject to fatigue, the concepts are demonstrated and validated.
