Resumen
En este proyecto de investigación se estudia el comportamiento sismorresistente de edificaciones con muros de hormigón armado de ductilidad limitada de tres edificios de 3 y 6 niveles construidos en Ecuador, Perú y Venezuela, respectivamente. Se evalúan las estructuras mediante un análisis lineal modal espectral, utilizando los parámetros y espectros de las normativas vigentes en cada uno de estos países. Este proceso se inició con una revisión de los datos de los planos estructurales que se poseían para el análisis. Se procedió a elaborar los modelos matemáticos del sistema estructural de las edificaciones en 3D, en donde se instauraron los espectros de diseño que corresponden a cada una las ciudades donde se encuentran ubicadas dichas edificaciones.
Se efectuó un análisis inicial y se evaluaron distintos parámetros de comportamiento sísmico como el periodo, las excentricidades y derivas, modos de vibración, control de desplazamientos, revisión de masa participativa, cortante dinámica de piso mediante la NEC -2015 para Ecuador, la RNE E.060:2020 para Perú y la COVENIN 1756:2001 para Venezuela, y se obtienen los diagramas de interacción de los muros estructurales y se verificar la relación demanda-capacidad. obtener la simulación del comportamiento de estas estructuras al momento de evaluarlas con los referentes sismos de diseño.
Se concluye que en Ecuador, Perú y Venezuela se han construido edificaciones en muros de hormigón armada de ductilidad limitada donde se confirma que de las tres edificaciones evaluadas los edificios de Ecuador y Venezuela cumplen los estándares normativos mientras que el edificio de Perú resulta ser sísmicamente vulnerable.
This research project studies the earthquake-resistant behavior of buildings with reinforced concrete walls of limited ductility of three buildings of 3 and 6 levels built in Ecuador, Peru and Venezuela, respectively. The structures are evaluated by means of a spectral modal linear analysis, using the parameters and spectra of the regulations in force in each of these countries. This process began with a review of the data of the structural plans that were possessed for the analysis. With the information, the mathematical models of the structural system of the buildings were then elaborated in 3D, where the design spectra corresponding to each one of the cities where these buildings are located were established. An initial analysis was carried out and different parameters of seismic behavior were evaluated such as the period, eccentricities and drifts, vibration modes, displacement control, participatory mass review, dynamic floor shear through the NEC -2015 for Ecuador, the RNE E .060: 2020 for Peru and COVENIN 1756: 2001 for Venezuela, and the interaction diagrams of the structural walls are obtained and the demand-capacity relationship is verified. obtain the simulation of the behavior of these structures at the time of evaluating them with the design earthquake referents. It is concluded that in Ecuador, Peru and Venezuela buildings have been built in reinforced concrete walls of limited ductility where it is confirmed that of the three buildings evaluated the buildings in Ecuador and Venezuela meet the regulatory standards while the building in Peru turns out to be vulnerable.
