The capacity deterioration of structures over time may impair their seismic structural reliability significantly, and, thus, they should be taken into account when assessing their seismic performance. In this study, a closed-form solution was proposed for time-dependent seismic reliability analysis of deteriorating structures. The capacity deterioration on the temporal scale was captured by the generalized capacity and deterioration function, and the Fréchet distribution was used to describe the probabilistic behavior of the peak ground acceleration. The deterioration of structural seismic ca...

This paper proposes explicit approaches for time-dependent reliability assessment of aging structures, taking into account the correlation associated with the load process and that arising from the resistance deterioration process. For the load process, temporal correlation may arise due to the impacts of underlying common causes. With this regard, a closed-form solution is developed for structural reliability, which models the sequence of load effects as a Markov process. Furthermore, the resistance deterioration is by nature a non-increasing stochastic process with autocorrelation on the tem...
