Desempeño de edificios especiales durante sismos en Ecuador - caso de estudio : catedrales, iglesias, templos para las provincias de Guayas y Manabí.

Abstract

For the following degree work, information was collected from different newspapers that circulate nationally and that have records of the earthquakes that have affected the provinces of Guayas and Manabí focusing on those that maintain their news center in the study areas. Similarly, magazines, national and international articles related to construction, websites, technical reports, soil studies and all the information that could be accessed to corroborate the results presented were consulted. The cathedrals, churches and temples that have presented structural and architectural damage during the different earthquakes that occurred in Ecuador since 1977 were identified and a list was created for case studies. For these cases, the earthquakes that have had more relevance on the structures are that of August 4, 1998 and April 16, 2016. Each case was studied, and the level of seismic risk was identified by hazard curves, also based on their vibration periods, it was possible to establish what type of earthquake affected the building: frequent, occasional, rare and very rare. To carry out site and design response spectra, data obtained from different accelerographic stations distributed in the provinces of study were used, these spectra allow us to know how much each structure moves and determine if it complies with what is established in (NEC - 15).
