Desenvolvimento de software de análise, dimensionamento e verificação de lajes retangulares de concreto armado

Resumo

The progress of theoretical knowledge and computational technology has enabled the development of
several methods for the analysis and design of structures. Reinforced concrete is still widely used today in several
structures, from bridges to buildings. Even in so-called composite structures (steel-concrete), slabs in reinforced
concrete are still used, since the material is the best choice in terms of plate behavior. In this way, the design of
slabs is still a current issue, and this procedure must guarantee that the final structure is safe from both the ULS
(Ultimate Limit State) and SLS (Service Limit State) points of view. In the context of slabs design and to assist
civil engineering students and newly graduated engineers, this work presents the development of computer
software for the design of reinforced concrete slabs, based on Visual Basic programming language for the
Windows operating system. This software uses design tables for obtaining internal forces in thin plates (Kirchhoff
theory), allows the design and verification of reinforced concrete two-way slabs in a fast and practical way. Such
implementations are confronted with classical examples, in order to prove the validity of the results obtained by
the software. Finally, the user can export these solutions to a text document, so that it can be easily interpreted and
manipulated. It should be noted that the design and verification procedures implemented in the software are in
accordance with criteria established by the Brazilian Standard NBR 6118:2014.
