ABSTRACT
In Chapter 3, several representative inspection and SHM techniques for fatigue-sensitive steel bridges and RC bridges under corrosion are reviewed. The effect of inspection and SHM on life-cycle cost analysis is described. The probabilistic approaches to predict the bridge reliability using the data from monitoring and to quantify the availability of monitoring data are reviewed. The effects of monitoring and prediction durations on the expected availability of monitoring data are provided. The expected damage detection time and delay, and probability of failure are formulated considering the uncertainties associated with the damage occurrence, propagation, and detection. The relations among the probability of damage detection of an inspection method, monitoring duration, and number of inspections and monitoring, expected damage detection delay and probability of failure are investigated. Based on the probabilistic concepts presented in this chapter, the life-cycle inspection, monitoring, and maintenance management planning can be optimized.
