As technology advances, developed countries conduct research based on the lessons learned from each earthquake. This research leads to updates in building codes, aiming to create safer structures that respond appropriately to seismic activity. The goal is not only to protect human lives but also to safeguard the economy by preventing structural collapses. This experimental study presents a comparative dynamic structural analysis based on the parameters of the NEC and ASCE 7-16 standards. The study evaluates the NEC’s capacity to ensure structural safety and efficient planning. To achieve this, a five-story irregular structure was designed using ETABS software, where structural models were developed: one following the NEC to calculate static and dynamic base shear, and another based on ASCE 7-16 to determine horizontal forces. The results obtained from both standards were compared in the dynamic analysis context. The findings reveal significant differences that must be carefully considered in structural design. According to NEC 15, the base shear values are below 1 percent, whereas when using ASCE 7-16, the calculation of base shear—considering both static and dynamic forces-exceeds 2 percent. Although this increase may seem minor, it can have a substantial impact on the design and safety of the structure, particularly in critical buildings or areas with high seismic activity. Therefore, the NEC should reconsider its safety standards to enhance disaster resilience, ultimately protecting both the well-being and economic stability of the Ecuadorian population.
