Análise comparativa entre modelos estruturais de edifícios com plantas baixas flexíveis

Abstract

Architectural designs with flexible floor plans are trends in the Brazilian real estate market and are increasingly present in developments in medium and large cities in the country. The ability to allow the user various configurations of their own home, such as living room enlargement, creation or expansion of bedrooms, option for kitchen or joining other rooms are current strategies used by builders to carry out innovative designs and meet the needs consumer However, designs with flexible floor plans suggest the elimination of beams inside some rooms, resulting in continuous slabs with cutouts, which makes it difficult to scale these structures due to stresses generated due to the irregular geometry of the slabs. Thus, the present work shows a comparative analysis performed in a seven-floor building, designed in three different ways with the Eberick software, varying the geometry of the slabs, to understand the behavior of the stresses in these structures and the consumption of concrete and steel in the slabs and beams of the three models processed. The results show that the concrete consumption in the three models varied little, on the other hand, the steel consumption increased by approximately 25% between the rectangular slab model and the more complex one, with continuous cutout slabs. The objective of this work is to show that flexible plants bring numerous advantages for the user, however the slabs with irregular geometries have more complex design, often resulting in increased cost of the work.
