Análisis de vulnerabilidad sísmica de la Unidad Educativa Ciudad de Machala, aplicando metodología fema-154 y Normativa Ecuatoriana de Construcción.

Abstract

The objective of this research work is to analyze the seismic vulnerability of a block of the educational unit, Ciudad De Machala, applying the FEMA P-154 methodology, Federal Emergency Management Agency, a qualitative method which consists of an evaluation by means of a Rapid Visual Screening Examination, RVS, This methodology is complemented with the application of the Ecuadorian Seismic Risk Construction, Evaluation and Rehabilitation of Structures Standard, NEC-SE-RE, in the Seismic Hazard and Seismic Resistant Design Standard, NEC-SE-DS, because we are based on the Z Factor by seismic zone, and the seismic region of the United States has other considerations to find the values of acceleration response in rock. In this way the form, high, moderate, low seismicity, to be used for this evaluation is selected. The most important factors to consider for the seismic vulnerability analysis are, year of construction, building area, height, elevation, irregularities in floor plan and the type of soil on which the building is located. The following form has an, S, scoring system, and the final result will be compared with the basic score of 2, this being a maximum value in the consideration of buildings with low performance to seismic performance, if the final, S, score obtained in the analysis is less than or equal to two, S ≤ 2, a more detailed evaluation should be considered.
