Evaluación y análisis estadístico de las principales causas que incidieron en el colapso y daño estructural de las edificaciones en la ciudad de portoviejo por causa del terremoto del 16 de abril del 2016.

Abstract

In this paper is focused on carrying out a statistical work of the main causes that influenced the collapse and affected structures in the buildings of the city of Portoviejo after having suffered an earthquake of magnitude 7.8 ° on the Richter scale on April 16 2016. The work has an analysis of 43 buildings that were evaluated by means of the rapid post-earthquake evaluation technique, in which casts of collapse, failure or structural damage were quantified by means of data tabulation and analysis. It elaborates in a text of nine chapters, from the approach of the problem until the development of the study and later conclusions and recommendations. In the first 2 chapters we establish the subject and carry out an instruction to the subject, delimiting it and establishing the antecedent of the same. In the third chapter, a varied theoretical framework is developed, ranging from the reality of the study area, type of constructions, informality in construction, municipal norms, to the seismic risk of Ecuador, the effect this produces on structures And finally the post-earthquake evolution. Moving on to the fourth, fifth and sixth chapters, the visualization of the study is developed, showing its social, economic and scientific contribution, establishing the hypothesis of study and defining the objectives achieved. Lastly, in the seventh chapter, we define the sample to be studied, so that data collection and analysis and tabulation of data are carried out in the 8th chapter, which in chapter 9 will serve to carry out our conclusions.
