Influencia de la mampostería no confinada en la rigidez y deformación de pórticos especiales a momento en edificaciones

Abstract

This thesis is based on the demographic growth and intense seismic activity in Machala, Ecuador, highlighting the importance of including non-structural masonry in structural calculations in buildings. It is emphasized that ignoring this element can lead to erroneous estimates of stiffness strength and safety in structures, increasing the risk of damage in the event of earthquakes and the costs of post-earthquake rehabilitation. The geographical characteristics, soil types. The problem of the lack of regulations and the scant interest in research on non-structural masonry is highlighted, leading to imprecise estimates in structural analyses. From this, scientific questions are raised to address the influence of masonry in structural analyses, the design criteria for an optimal prediction of structural behavior, and the appropriate methodology for the design of special moment frames. Finally, the study focuses on the contribution of the stiffness of non-structural masonry in seismic events and justifies the influence that unconfined masonry has on structures, thusproviding greater protection to the population and urban sustainability in Machala.
