Análisis del comportamiento sísmico de una estructura de hormigón armado mediante el uso de disipadores BRB

Abstract

In this degree work, the analysis of the seismic behavior of a reinforced concrete structure equipped with BRB (Buckling Restrained Braces) dissipators in the city of Guayaquil, Ecuador, is addressed. The main objective is to evaluate the efficiency of these devices in the reduction of deformations and seismic forces in the structure, and to determine their impact on the safety and seismic resistance of the structure. A numerical approach will be used to simulate the behavior of the structure under different seismic conditions, using specialized structural modeling software ETABS. The results obtained will allow analyzing the seismic response of the structure in terms of displacements, forces and deformations, and assessing the effectiveness of the BRB dissipators in reducing seismic damage. The study will focus on the evaluation of the capacity of the structure to resist seismic forces, considering the stiffness and damping coefficients. The results will be analyzed in terms of current standards and regulations, such as the Ecuadorian Construction Standard (NEC-15) and ASCE-7-16, to ensure the safety and optimum performance of the structure. The results of this study will be of great use to civil engineers and architects who design and construct buildings in seismic zones, as they will provide valuable information on the effectiveness of BRB dissipators in reducing seismic damage. In addition, the results are expected to improve the safety and seismic resistance of structures in the city of Guayaquil, and to reduce the risk of damage and human losses in the event of an earthquake.
