Estudo comparativo entre sistemas estruturais com laje lisa maciça e lisa nervurada em um edifício comercial

Abstract

Given the significant technological evolution in the construction sector, it is possible to observe the search for structural solutions that aim to supply disadvantages left by old solutions and methods, also ensuring more economy and safety to projects. In view of this, it is of great importance to know and analyze the behavior of structures and how this is modified with the use of various possible configurations, with the purpose of understanding how they are more efficient and defining the best solution to be employed in a specific project. That said, this work aims to perform a comparative study between two structural systems, one with massive flat slabs and the other with ribbed flat slabs, for a commercial building of 6 floors and obtain the solution with lower consumption of materials for the case analyzed. To this end, the structural design was elaborated with the aid of the Eberick software and the comparison was made based on structural parameters and, especially, on the consumption of steel and concrete. With the results, such as displacements, flaming moments, cutting effort and consumption of materials, it was observed that the system composed of ribbed flat slabs was the one that presented the lowest consumption of steel and concrete. Thus, it was concluded that the ribbed flat slabs are the most viable for the analyzed building.
