“…Instead, reliability and resilience assessment is a powerful tool to quantitatively measure the structural ability to fulfill service requirements, based on which planners and decision‐makers can optimize the maintenance strategies and allocate limited resources wisely. Structural reliability is defined as the probability of survival (withstanding external load effects), 8–10 while resilience is indicative of structural ability in terms of preparing for and adapting to hazardous events and recovering rapidly from the disruptions 11–15 …”

“…Structural reliability is defined as the probability of survival (withstanding external load effects), [8][9][10] while resilience is indicative of structural ability in terms of preparing for and adapting to hazardous events and recovering rapidly from the disruptions. [11][12][13][14][15] Among the early attempts to derive a closed-form solution for time-dependent reliability is the work by Mori and Ellingwood, 8 which considered the impacts of structural resistance deterioration and the randomness associated with the load process. For a reference period of t [0, ] l , modeling the load occurrence as a stationary Poisson process, the time-dependent reliability, R t (0, )…”

Earthquakes are among the natural hazards threatening the serviceafbility, functionality, and safety of engineering structures significantly. Posthazard structures may suffer from different damage states and correspondingly different functionality losses/recovery processes in the aftermath of hazardous events. This paper proposes a measure for structural time‐dependent seismic resilience considering multiple damage states. Its specific case (i.e., considering damage–no damage scenario) reduces to the existing resilience measure in the literature. The time‐variant fragility curves and the generalized seismic capacities are used to determine the damage states conditional on the peak ground motion (PGA). The proposed measure is applicable for both of the following two cases: (1) the earthquake occurrence rate and the magnitude of PGA conditional on earthquake occurrence are known; (2) the probability distribution of annual maximum PGA is known. In terms of the latter, the annual seismic hazard function can be used to describe the seismic load uncertainty. A numerical example is presented to demonstrate the applicability of the proposed resilience measure. It is shown that the proposed measure can be used to quantitatively guide structural design to meet the target resilience level.
