    Metodología para la consideración de la torsión en planta en la evaluación sísmica de edificios de hormigón armado típicos en la ciudad de Cuenca
    (2018) Aguirre Arias, Bernarda Priscila; Flores Verdugo, Pedro Fernando; Jiménez Pacheco, Juan Carlos
    The city of Cuenca is located on an area with high seismic hazards, PGA=0.25g, according to the Ecuadorian Construction Standard. The history of seismic activity in the sector reveals disasters caused by at least one earthquake of magnitude 7 (February 1913), implying probable seismic scenarios to arise in different construction typologies of the city, such as structures reinforced concrete. Historically, since of the eighties, the structures respond to breach system and flat slab. The structure plant configuration has not been of great relevance at the moment of analyzing its behavior in front of an earthquake, for which it expects buildings with different degrees of asymmetry, leading to torsion problems in plant. The methodology of consideration of the torsion in plant is presented based on a statistical analysis of buildings with a frequent plant configuration, through schemes and architectural plans, establishing typical patterns of distribution of structural elements and indices that indicate the potential torsion in plant, for a future seismic evaluation by non-linear static methods, -pushover-, that consider the torsional effect produced by the movement of the soil, as a strategy for assessing the performance of buildings. The result is the point of intersection between the capacity curve obtained from the pushover analysis, -relationship between the basal shear and superior displacement-, and the elastic response spectrum. Subsequently, a comparison is made between the methods to define the best relevant methodology to the cases of the city of Cuenca.
