PUJOL, Santiago  and  RODRIGUEZ, Mario E.. Evaluating the behavior of nonstructural walls in Mexico-City buildings in the september 19, 2017 earthquake. Ing. sísm [online]. 2019, n.101, pp.53-66.  Epub Apr 30, 2020. ISSN 0185-092X.  https://doi.org/10.18867/ris.101.529.

The response of masonry infill walls to motions caused by the September 19, 2017 earthquake in Mexico City is evaluated. Plausible reasons for the observed damage are studied. Changes to design codes used in Mexico and Latin America are proposed to try to produce more acceptable behavior of buildings in the design earthquake and in earthquakes of smaller intensity such as the earthquake of September 19, 2017. Estimates of story drift are obtained using an acceleration record from this earthquake and the results are compared with allowable drift for a generic case and for two specific examples.

Keywords : masonry; partitions; earthquake; drift.
