GUTIERREZ TREJO, Juan  and  AYALA MILIAN, Gustavo. Resilience seismic analysis of buildings. Ing. sísm [online]. 2022, n.107, pp.47-73.  Epub Aug 29, 2022. ISSN 0185-092X.  https://doi.org/10.18867/ris.107.603.

In this paper, a probabilistic methodology to estimate fundamental decision variables of the theory of seismic resilience of buildings is presented: repair costs, repair time, recovery time and number of workers needed to perform the rehabilitation works. The proposed evaluation scheme is based on the recursive PERT method and is consistent with the probabilistic methodology for evaluating performance proposed by PEER and with the concept of resilience developed by MCEER. To illustrate the methodology, the evaluation of a seven-story reinforced concrete building with unreinforced masonry infill walls and designed in accordance with the Complementary Technical Norms - Seismic Design (2020) is presented. This structural system is typical of office buildings. The proposed methodology can be used to increase the seismic resilience of buildings, and to establish mitigation and recovery strategies not only for individual buildings, but also for groups of buildings.

Keywords : Structural resilience; repair and recovery time; repair costs.
