Monitoring Based Reliability Analysis and Damage Prognosis
This chapter explores advances in the fields of usage monitoring, probabilistic deterioration modelling, reliability assessment and optimal maintenance strategies of existing civil engineering structures. First, usage monitoring, such as load and environmental condition monitoring of a civil structure in service is discussed. From the monitored data, several probabilistic approaches are presented for stochastic deterioration modelling with uncertainty. Lifetime distributions representing probability of condition failure are obtained from various stochastic processes or predictive models, such as the Markov process, gamma process and Weibull model. Time‐variant reliability associated with limit states of the structure is assessed by various methods with consideration of changes in loads and resistances over time. Several techniques are offered for determining an optimal maintenance strategy through time‐variant reliability analysis and lifecycle cost analysis. Finally, a case study on usage monitoring and fatigue reliability assessment of a suspension bridge is discussed.
