Análisis Comparativo del Diseño Estructural de un edificio de hormigón armado utilizando la NEC-SE-DS, 2015 y propuesta de actualización NEC-SE-DS, 2024

Abstract

The purpose of this research work is the comparative analysis between the seismic specifications of the current Ecuadorian standard NEC-SE-DS, 2015, and the proposed update NEC-SE-DS, 2024, applied to a high-rise building, within the chapter of Seismic Hazard and Seismic Resistant Design. The evaluated building is not assigned a precise geographical location. Instead, its analysis is conducted across a range of representative soil types prevalent within the Metropolitan District of Quito. This methodology facilitates the identification and comparison of differences arising from the application of various design response spectra. The possible increased demands will be used to compare both standards and help identify changes in seismic risk. The structural analysis for this research is performed using ETABS software. This program facilitates the creation of numerical models with predefined dimensions, incorporating diverse structural characteristics. Through these models, the aim is to obtain comprehensive results regarding structural behavior and to quantify the percentage of variation attributable to the updated design factors.
