    Influencia del grado de simetría y la disposición equidistante de los pilares sobre los modos de vibración de una estructura de mampostería no reforzada típica del Centro Histórico de Cuenca
    (Universidad de Cuenca, 2020-08-12) Llivisaca Mejia, Juan Manuel; Jiménez Pacheco, Juan Carlos
    Santa Ana de los Cuatro Ríos de Cuenca, the capital of the Azuay province was founded on April 12, 1557. Since then, there have been many changes in the urban sprawl of the city and particularly in its Historic Center (CHC) (Jiménez, 2002). Because the city is located in an area of high seismic threat (Jiménez, Cabrera, Sánchez, & Avilés, 2018) and considering that the building material that was imposed since 1970 in the CHC has been brick (Jiménez, 2002), is taken as a working basis: Evaluación sísmica de edificios de mampostería no reforzada típicos de Barcelona: modelización y revisión de la aplicación del Método del Espectro de Capacidad (Jiménez, 2016). This research is used to compare the results obtained by the Red Sísmica del Austro (RSA) on prototypical unreinforced masonry buildings (URM) of the Cuenca Historic Center (CHC) (Jiménez, Cabrera, Sánchez, & Avilés, 2018), where the almost independent behavior of the resistant walls of the building is evident (modal behavior) as indicate Lagomarsino, Camilletti, Cattari, & Marino (2018) for irregular URM buildings with flexible floors, making it difficult to assess their seismic response using methodologies based on nonlinear static analysis (Quagliarini, Maracchini, & Clementi, 2017). On this basis, it is proposed to identify the influence of some geometric variables and mechanical characteristics on the building on the global dynamic behavior of an URM structure in terms of the form of its vibrational modes. Consequently, the dimensions of the spans between the walls, the symmetry of the building in terms of the stiffness of its structural elements and the transmission of lateral loads due to the existence of flexible floor diaphragms are analyzed
