ORTIZ SOTO, David  e  REINOSO ANGULO, Eduardo. Business interruption time in Mexico City due to direct damages and indirect effects in buildings due to the earthquake on september 19, 2017. Ing. sísm [online]. 2020, n.spe104, pp.1-31.  Epub 10-Mar-2021. ISSN 0185-092X.  https://doi.org/10.18867/ris.104.538.

After the earthquake on September 19, 2017 in Mexico, many businesses established in Mexico City stopped operating temporarily and even definitely. According to what was observed after this destructive event, in this work the sources of business interruption are identified: Initial security protocols, Suspension of public supply services, Neighborhood effects and Damages in the components of the building, and a model is proposed to determine the business interruption (BI) time, considering the inactivity of the building. In order to have reference values for the input data, the times of evaluation of buildings, restoration of public services, demolition of buildings, among other relevant aspects for Mexico City are documented. Finally, the concepts are exemplified with a hypothetical formal business established in a building with two levels of confined masonry and in the results it will be obtained that there would be a total stoppage of business activities for more than a month due to minor damages in the electric power infrastructure and some structural damage on the ground floor. In addition, it is concluded that, although business interruption depends on multiple factors, the participation of Structural Engineers is essential to minimize BI time, especially in the evaluation of the safety of buildings and the rehabilitation of infrastructures.
