Desenvolvimento de um software para o dimensionamento e detalhamento de lajes maciças retangulares de concreto armado

Abstract

This work has as main objective the development of a program to make the determination of efforts on massive slabs of rectangular or square geometry and also the dimensioning and detailing. The use of Visual Basic language enables the development of a software in Windows environment with enough practice and simple graphical interface to learn. Parallel to the development of the software presented, was conducted a literature review to find ways to automate the necessary calculations and support theoretically the whole computational solution proposal. Slabs, according to ABNT NBR 6118:2014, should be checked in the State and limit the service limit State. For the verification of the limit State last, was used the theory of Plastic Hinges for armed slabs in two directions. For armed slabs in one direction, the calculation is made by analogy to a beam, assuming a unitary width range. Sizing examples were designed to validate the software. Such examples have also been resolved by manual calculation and are exposed in this work
