Estudios de las causas de demolición de edificios afectados por el sismo del 16 de abril de 2016 en Chone.

Abstract

In this work, information regarding the buildings that were demolished after the earthquake7 of April 16, 2016 in the city of Manta (Ecuador) is presented, selecting the most interesting cases to analyze the causes of demolition. To carry out the analysis, the elastic response during the earthquake of single degree of freedom system with vibration period similar to those of the buildings, was calculated using the Ecuadorian Construction Standard (Nec- 15). On the other hand, and using the NEC-15 code and codes used for construction of such buildings the seismic design factor, seismic design factor8, the inelastic9 drifts10 and the effective reduction factor (R) for every structures11 were found. Therefore, once the before mentioned results were obtained, an evaluation of technical reasons for demolition was performed. Finally, some technical criteria to decide on demolition or recovering of buildings affected by earthquakes in Ecuador were established.
