Influencia de los elementos no estructurales en el período natural de vibración en edificaciones con sistema de resistencia sísmica combinado ubicadas en la ciudad de Bucaramanga, Santander

Abstract

This study explores the influence of non-structural elements (NSC) on the natural vibration period of earthquake-resistant buildings with combined structural systems, using buildings located in Bucaramanga, Colombia as a case study. Through a comparative analysis, we seek to identify how the inclusion of NSCs impacts the dynamic behavior of these structures, based on models developed with the ETABS software and on previous studies carried out by [1]. The research follows a quantitative approach, modeling seven representative buildings from the previous study, where the inclusion of NSCs was considered. The results obtained were compared with those presented in [1], to evaluate the consistency and variability in the conclusions. The results indicate that, in line with the observations of [1], the inclusion of NSCs has a notable effect on reducing the natural vibration period of buildings. On average, a significant reduction of 43.81% was observed in the models that included NSC, which highlights the importance of considering these elements in the evaluation of the seismic behavior of structures. However, it is important to interpret these findings in the context of the simulations carried out, which provides a basis for future research that delves into the interaction between NSCs and earthquake-resistant design.
