Seismic behavior of the structure of the convent San Juan Bautista de Tetela del Volcán, during the earthquake on September 19, 2017, with its epicenter in Axochiapan, state of Morelos, Mexico

Resumen

This work describes the seismic behavior observed during the earthquake that occurred on September 19, 2017 in the convent of San Juan Bautista de Tetela del Volcán. Several records of accelerations obtained in this seismic event with epicenter in the vicinity of Axochiapan Town, Morelos State, Mexico, are analyzed, and the one considered representative of the movement of the seismic phenomenon in the site is selected. With this record, the seismic behavior observed in the structure of the Temple and Convent under research is studied.Field research consisted of structures studies and geophysical assays with non-destructive tests, which allowed to determine propagation velocities, dynamic elastic modules and periods of vibration of both the soil and the structure. Due to the heterogeneous characteristics of the masonry, the study was carried out through numerical analysis techniques that incorporated in their approach the non-linear behavior of the structure through the use of the Abaqus CAE program. The results of the resistance and deformation demands were analyzed, as well as the results of the eld evaluation of the damage level of the structure, comparing the behavior of the structure during the seismic event and the theoretical model of nonlinear analysis performed. The possibility is raised that this type of analysis can predict the seismic behavior of heritage monument structures, for mitigation actions that can be carried out before seismic events.
