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

Abstract

In the present research work, by means of information gathering, all the buildings that were affected by the earthquake of April 16, 2016 in the city of Bahía de Caráquez are studied, selecting five specific buildings that did not show evident causes for its demolition. The collection of information was through newspapers, technical articles, verbal information exchange with professionals, photographs and evaluations of the buildings carried out by Soleico and Plan Procons consultancies. Once enough information was obtained from the selected buildings, the calculation memory of the acceleration and the elastic displacement corresponding to a system of 1 GDL with vibration period equal to that of the buildings, the maximum inelastic drift, the inelastic mezzanine drift by the Miranda 1999 method and the R (effective) relating the current standard (NEC-15) with the codes of the years of design of the buildings (CEC-79 and CEC-02). With the results of the calculations, it was concluded if they had sufficient technical reasons to demolish the buildings, the criteria applied by the consultants were reviewed to recommend demolition, the results of the maximum lateral deformations were contrasted according to the method proposed by Dr. Miranda in 1999 with the results obtained using the NEC-15 and some recommendations were given on the NEC-15 for a better earthquake-resistant design.
