A Time-Variant Reliability Analysis Method Considering Maintenance

摘要：

　　A time-variant reliability analysis method taking into account the maintenance is proposed in this paper.The effects of maintenance on structural resistance and resistance decay function are first quantified by repair functions.A new time-variant reliability model that are capable of considering maintenance is then established by integrating the repair functions.A solution strategy based on stochastic process discretization is then formulated to calculate the time-variant reliability.A reliability-based optimization approach for designing maintenance strategy is further presented.Finally,three numerical examples are investigated to verify the validity of the proposed method.
