Análisis y evaluación sismorresistente de edificaciones previos a la creación de la Normativa NEC-SE-DS: estudio de caso en la Facultad de Filosofía de la Universidad de Cuenca

Abstract

This degree work addresses the urgent need to analyze and evaluate the seismic resistance of buildings constructed before the implementation of the "NEC-SE-DS" standard. The building of the Faculty of Philosophy, Letters and Educational Sciences of the University of Cuenca, erected in 1956, has been selected as a representative case study. The age and essential function of this building make it crucial to verify its compliance with modern seismic-resistant design standards to ensure the safety of its occupants during seismic events. The evaluation is carried out using a force-based methodology, in accordance with the Earthquake Resistant Design section of the Ecuadorian Building Code. First, the lateral seismic forces affecting the building structure are determined. Subsequently, a detailed modeling is performed using SAP 2000 software to analyze the structural response under seismic loads, observing critical deformations and displacements. Finally, the maximum deformations are calculated and compared with the admissible limits established by the regulations. This analysis will make it possible to determine whether the building complies with current seismic-resistant design requirements and, therefore, whether it is capable of providing a safe environment for its occupants in the event of an earthquake.
