Influência da utilização de pilares-parede nos coeficientes de estabilidade global de uma edificação de múltiplos pavimentos

Abstract

As population density has increased around the world, the construction of multi-story buildings has become commonplace. With the advancement of construction techniques and methods, it is possible to apply different structural models to the same building, making it essential to always analyze the overall stability of the structure and the most effective and viable method. This work sought to analyze the variation in the overall stability parameters of nine reinforced concrete structural designs, varying the use of wall-columns and their location in the building. These designs were verified for buildings with 9, 12, and 15 stories. Furthermore, the quantity of steel and concrete used in the superstructure of the models was verified using the TQS structural calculation software. The use of wall-columns proved to be the most viable solution, either centrally located or used on the sides of the building, depending on the structural arrangement under analysis and the number of stories. A comparative analysis between the different structural arrangements addressed is fundamental.
