Estudio comparativo del análisis estático no lineal de estructuras regulares de hormigón armado aplicando normativa Ecuatoriana, Colombiana, Peruana y Chilena

Abstract

Over time, it has been observed that in Latin America there have been several seismic phenomena, which produce structural damage and even the collapse of the structure itself, as well as the death of several people. In this article, an investigation based on seismic performance was carried out by applying a nonlinear analysis of two regular buildings of 5 and 7 floors located in border areas that present higher seismicity and have similar soil characteristics. Therefore, the following regulations were taken as reference: Colombian Earthquake Resistant Construction Regulations (NSR-10), the Ecuadorian Construction Regulations (NEC-15), in Peru the National Building Regulations (RNE) and the Official Chilean Regulations and Supreme Decree 61 (NCh-DS61). For this purpose, 12 modeling were generated, 2 for each border area, using a computational package. First a static and dynamic analysis was performed, and then a nonlinear analysis (Pushover) considering the FEMA and ASCE 41-13 regulations, to obtain each capacity curve, performance point and performance level. The results indicated that applying the NCh433 standard has a better behavior against a design earthquake obtaining a level of functional performance, applying the RNE standard has a level of performance that protects life safety and applying the NEC and NSR standards do not have an adequate behavior in a high seismic zone giving a level of performance in collapse prevention or collapse.
