Earthquakes are a significant threat in countries with high seismic activity such as Peru, Chile, and Colombia, where the application of earthquake-resistant regulations is essential to ensure structural safety. The objective of this research is to determine the discrepancies in the use of criteria and designs of the earthquake-resistant regulations E.030 versus Nch433 and NSR-10, as well as how these affect loads, drifts, and accelerations. This is obtained through a comparative analysis of basal shear forces, story drifts, and spectral accelerations. Therefore, a model of a two-story confined masonry house located in San Juan de Miraflores, Lima, is made using Etabs software and complying with the minimum requirements of standard E.070. NSR-10 showed the greatest strength. basal shear with a value of 422.94 Tonf on both the “X” and “Y” axes by means of analysis Linear static. O...
