Relación estadística de la coincidencia del período de vibración de suelos y edificios con el grado de daños de edificios durante el sismo del 16 de abril de 2016 en la costa del Ecuador.

Abstract

The investigation was carried out with a total sample of 50 buildings, which were affected during the 7.8 MW earthquake on April 16, 2016 occurred in Pedernales City (Ecuadorian coast). These buildings belong to five cities in the region: Pedernales, Chone, Portoviejo, Manta and Guayaquil. For statistical analysis purposes, it was necessary to recognize the characteristics of the sample, such as period of vibration, type of soil and degree of damage generated, information collected from past degree thesis, calculations following the NEC - 15 regulation and with the soils zoning maps of each city and, in this way, being able to calculate the spectral acceleration through the Response Spectrum of each city during the earthquake. This last piece of information was used to prove the hypothesis "The classification of the degree of damage as moderate or severe is independent of Sa" using the Chi-Square method of data independence. In such manner, the expected results were reached and the respective conclusions and recommendations were made as well.
