Análisis de vulnerabilidad sísmica estructural del centro educativo Licenciado Diego Minuche Garrido en la Ciudad de Machala

Abstract

The main objective of this research work is to analyze the structural seismic vulnerability of the classroom block of the Diego Minuche Garrido School in the city of Machala, taking reference in the Ecuadorian Construction Standard, in which in the NEC chapter - SE –RE Seismic Risk, Evaluation, Rehabilitation of Structures, it is recommended to use the Manual QUICK VISUAL CHECK OF BUILDINGS FOR POTENTIAL THREAT THREAT proposed by the Federal Emergency Management Agency FEMA 154. The methodology by the FEMA 154 method is a qualitative method, which is based on a visual inspection and building data collection. For the choice of the form high, moderate, low seismicity, of the FEMA 154 method for the analysis of structural seismic vulnerability, we rely on the Z Factor by seismic zone, which is provided by the NEC 2015. In this form the vulnerability is the determined by an index or final score S which is determined from the initial score based on the type of construction of the 15 different types that are outlined. Other important factors to consider for the analysis of structural seismic vulnerability such as height, elevation, irregularities in the plant, year of construction, construction area, type of soil, land use. If the fine score Sbtained in the analysis is less than or equal to two S ≤ 2, a more detailed evaluation should be considered.
