Análise e dimensionamento de laje lisa em concreto armado por modelo simplificado segundo a NBR 6118/2014

Abstract

This work deals of design and analysis of Flat slabs with reinforced concrete, model used unobtrusively in Brazil, being increasingly used because of its ease in the application and particularly the need to increasingly have layouts more flexible besides a range of other advantages. In this context inserted, flat slabs with reinforced concrete needs a proper study and detailed analysis according to the Brazilian standard, NBR 6118/2014, which sets the standard for design of reinforced concrete structures, where it operates the context of flat slabs. This work has aimed to make an analysis of the regulatory standard as a model for the design of flat slabs, using simplified elastic model and the distribution of moments to calculate the structure and design according to the standard. So they are checked such procedures, and apply the concepts of it in a hypothetical structure, comparing their results with what was found in Eberick v8 software, which is used in a calculation model more complex (Grid analogy method), making the design for each model adopted in this case, and then checking the feasibility of the structure, situations that are conducive to this type of slabs, discussions of results, etc. Therefore, the software is very useful tools and should be used judiciously and responsibly, used as an auxiliary tool, correcting results and assisting in design, checking and giving more security and fidelity to the calculation made according to NBR 6118/2014
