Comparar mediante un análisis multicriterio ahp la ductilidad de tres tipologías estructurales, identificando vulnerabilidades sísmicas en la zona centro del ecuador

The analysis of buildings under seismic movement must consider two main aspects of structural displacement. The first would be the structural deformation, and the second the behavior of the rigid body of the structure. This effect produces a modification in the inelastic behavior of the systems. Considering the flexible base can change the distribution of the internal forces that act on the structure, generating variations in the ductility demands in the different structural elements (Fernández Sola, 2018). This proposed research sought to compare levels of flexibility and structural efficiency in mixed multifamily buildings located in the central zone of Ecuador that share seismic considerations. It had been designed under the Ecuadorian Construction Norm, subjecting them to a static non-linear progressive plasticization analysis (Pushover) searching through the capacity spectrum for the natural flexibility of the structure and the validity of the evaluation of the stresses generated by the action of the design earthquake. Finally, a comparison had validated by a process that had been carried out in the decision-making development; which is the multi-criteria hierarchical analysis (AHP) establishing comparison criteria for each structural typology presented, reinforced concrete, structural steel, and structural steel with concentrically braced frames, defining which of these typologies achieves a better performance.
