Evaluación de los niveles de desempeño para pórticos rellenos de mampostería.

Abstract

The presence of the Masonry Filled Porticos (PRM) predominates in the designs of the structural buildings built in the country, in addition to the use of uncontrolled masonry. The effects that the magnitude and distribution of forces applied directly in the PRM, such as a seismic force, can have, are ignored at the time of analysis of these buildings. As a result of recent events in the country, the 7.8 Mw earthquake, which occurred on 16 April, was found to have caused damage to PRM of several structural buildings, failed to achieve an appropriate level of performance for the safety of individuals From the calculations, graphs, hysteresis and trial data that were obtained from (Chiozzi & Miranda, 2017), (Morandi, Hak, & Magenes, 2018), (Crisafulli, 1997), (Sigmund & Penava, 2014) among others, it will be possible to obtain the behavior of the PRM of a structure, resistance parameters, geometry and detail, in addition to efforts, taking into account the presence of voids intended for doors and windows, where the contribution of rigidity varies, thus modifying the performance that guarantees us a good safety of life. The results are compared to determine the most influential parameters in the force - deformation and the relationship between deformation vs damage. Therefore, it is committed to develop this study to define the performance levels of masonry fillings in terms of drift.
