Abstract This paper presents a methodology to quantify a proposed parameter defined as expected annual seismic resilience, which takes into account all possible events that affect a site of interest by following the next steps: (1) definition of seismic hazard, (2) definition of the exposure database, (3) computation of structural and human vulnerability, (4) estimation of seismic risk, (5) definition of rehabilitation strategies and (6) estimation of repairing times and required resources in the proposed rehabilitation process. In this study, consequential physical losses and indirect cost are not considered in the resilience computation. The methodology is applied to a case study of existing school buildings, located in Mexico City given its important seismic activity. The results are presented in annual resilience maps that will allow to graphically observe the distribution of resilient structures and use this information to take better decisions in disaster prevention and response. From this research it was found that a large percentage of the studied school buildings do not achieve an acceptable annual resilience value according to the rating proposed, which is important, since the seismic design codes do not explicitly consider resilience concepts. However, with the information of expected annual seismic resilience values in Mexico City, obtained in this research, it is possible to identify those buildings that require immediate attention associated to the lower resilience values so that they may be taken into consideration in the decision-making process of disaster prevention and response.

1 Introduction The steady socioeconomic development in Mexico has led to an increase in the social infrastructure. With the increasing infrastructure, the number of the exposed assets becomes larger, hence natural disasters have a major effect on the quality of life by changing the functionality level of certain systems (e.g., houses, schools and hospitals). Particularly the education sector in Mexico has suffered considerable losses during seismic events, such as the M8.1 earthquake of September 19th 1985 or the recent events occurred in September 7th and 19th in 2017, where an important number of school buildings were severely damaged (SEP 2017; INEGI 2017) and in some cases, those damages leaded to important socioeconomic losses, disruptions in t
