The analysis of the overall stability of the structures is highly important in the field of civil construction, since the trend towards the construction of taller and more slender buildings has only increased in the country. This work portrays a study on global stability, carried out in a building of multiple reinforced concrete floors considering the rigid core as a bracing system. To make the study feasible, three dimensions were made with different positions of the rigid core: centered on the building, eccentric on the largest side of the building and eccentric on the smallest side of the building. The analysis of global stability was performed using the γ_z coefficient, which also allowed to classify the structure as to the types of nodes. Analyzes were also carried out regarding the consumption of materials such as steel, concrete and shapes of the buildings studied. This research concluded that the rigid core located in the center of the building presented better results than the other locations with respect to global stability. The study of the material consumption carried out did not make it possible to determine precisely which project has the best cost benefit due to the alteration of the rigid core, which makes a more detailed study necessary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
