Desempeño de edificios especiales durante sismos en Ecuador - caso de estudio : escenarios deportivos de las provincias de Manabí y Esmeraldas.

Abstract

The purpose of this work is to determine the performance of special buildings during earthquakes in Ecuador from 1997, focusing on sports venues such as stadiums, sports complexes, coliseums, etc. in the provinces of Manabí and Esmeraldas. Many of these special structures have suffered damage during these earthquakes, in this way it is possible to determine the parameters that affected their seismic performance, by collecting information from the sources available for analysis where it was possible to show damage and failure in the construction of these buildings. It was possible to establish the type of soil where these structures are located and thus be able to prepare the corresponding acceleration response spectra by mean of Seismic Hazard Curves that reflect the acceleration in PGA rock, as well as the elastic response spectra of acceleration design. The values of inelastic drifts and vibration periods of each structure were obtained so that through the use of the accelerometer records of cities it was possible to conclude what type of site earthquake occurred for each case. The calculation of the effective R factor was performed with the records of the design response spectra measured in accelerations and the response spectra for design of the stations, this research process was carried out with the purpose of evaluating the seismic performance of these buildings based on the parameters of the 2015 Ecuadorian Construction Standard for earthquake-resistant design and if these parameters are safe for this type of special structures.
