Estudio de las causas de demolición de edificios afectados por el sismo del 16 de abril de 2016 en Pedernales.

Abstract

The causes of the demolition of buildings affected by the earthquake of April 16, 2016 in the city of Pedernales, Province of Manabí, were studied. The respective investigation was carried out in newspapers, technical articles, technical reports and photographs of the affected buildings, where buildings were found which required the reasons for their demolition. We proceeded to send letters to public entities such as the Municipal Autonomous Decentralized Government of Pedernales and MIDUVI, to request information on the causes of the demolition of the buildings. This information was only partially obtained due to lack of effective response from public entities. The project was continued with the determination of the type of soil where the buildings were located, obtaining seismic record of accelerations, the elastic response spectra of acceleration of 1 GDL systems during the earthquake, the elastic response spectra of displacement, the drift maximum inelastic, the design seismic coefficients and the reduction value of the effective elastic response R that the buildings had during the earthquake. These analyzes were based on the 2015 Ecuadorian Construction Standard and the regulations in force in the year of construction of each building. Once these results were obtained, we proceeded to assess if there were technical reasons for demolition and how the results of this study can help to establish parameters for future decisions on the demolition or recovery of buildings affected by earthquakes in Ecuador.
