Revisión del comportamiento durante el sismo del 16 de abril de 2016 de edificios en hormigón armado afectados por el sismo del 13 de mayo de 1942.

Abstract

In the following work, 21 buildings were analyzed from the city of Guayaquil, Ecuador, which were affected by the earthquake of May 13 of 1942 and April 16 of 2016. For the work, interviews were requested with the experts and people in charge of different institutions like the Municipality of Guayas, University of the Arts (since this is the current one in charge of multiple buildings of the city), etc., to be able to extract information about the current state and repercussions left by the mentioned earthquakes, which was obtained without great difficulty. To determine the type of soil for the 21 structures, a paper from Dr. Xavier Vera Grunauer was implemented; the periods of the structures, the obtaining of the seismic record of the event of April 16, 2016, the spectra of elastic response of acceleration and displacement of design, spectra of elastic response of acceleration and displacement of design for the earthquake of 16/04 / 2016, the Sa for a system of 1 GDL with T equal to that of the building and elastic design response and for that of the earthquake of 04/16/2016, maximum inelastic drifts and the values of reduction of the effective elastic response "R". A comparison of the effective R values, obtained from the calculations, and those corresponding to the NEC-2015 is shown. Once the above mentioned has been calculated, a summary table with these data and an observation about the real damages caused by the event is presented.
