“…Hall and Giglio [17] emphasize the relevance of proper target resilience values and suggest that cost analysis may lead to optimal targets. Other researchers [18,19] that have oriented their efforts to propose a seismic resilience-based design have recommended target post-earthquake scenarios, such as Immediate Occupancy (IO), Rapid Recovery (RR), and Collapse Prevention (CP); nevertheless, there are no explicit discussions regarding the specific resilience or downtime values associated with such target scenarios.…”

“…Despite the current contributions, there are still opportunity areas in seismic resilience assessment and its interpretation. For instance, current studies present important simplifications such as estimating indirect losses as a fraction of direct losses [4,7] and the lack of a proper interpretation of the resilience values found [4,19]. For the above reasons, this paper presents a procedure to define expected recovery times, expected delay times, and expected functionality loss curves to be used in the seismic resilience assessment of buildings.…”

Concerns about prolonged downtime and functionality losses observed after recent seismic events have made it clear that seismic design is heading towards a resilience-based approach. However, there is still currently no clear consensus on how to quantify and interpret resilience. In this document, a probabilistic approach to estimate recovery times and functionality loss in buildings is presented, which allows for the estimation of seismic resilience through consideration of delay times and the behavior of non-structural elements. To achieve these goals, simple models that associate structural response and the resilience parameters (recovery time and functionality) are defined. The proposed approach was implemented in a database for public school buildings in Puebla City, where the expected times and functionality were obtained, thus allowing for quantification of the seismic resilience of each structure. Furthermore, target values for low and high resilience are proposed, which helps to identify the weakest elements in the educative Mexican infrastructure. The results showed that the inclusion of delay times and non-structural elements in resilience quantification is mandatory if an overestimation of resilience values is to be avoided. At the same time, the target values allow for the different structures to be categorized according to the resilience values obtained, finding that a significant portion of Mexican school buildings are underprepared in a resilience context.
