Cálculo prático de vigas em concreto armado

Abstract

Concrete is a material that resists compression forces, but resistible little traction, its tensile strength is about 1/10 of its force compression. That is, usually present in the structures, some structural elements are subjected to traction and compression, thus appeared reinforced concrete, basically two joining materials which complement one another. Thus, the compression-resistant concrete and steel to resist traction, with this combination reinforced concrete becomes a construction material, one of the most important structural elements. It is used in the structures of buildings, bridges, houses, shops, warehouses, churches. This document provides a roadmap of pre-design and design of reinforced concrete beams subjected to simple bending. The form of development of practical tables beams - reinforced concrete - the simple bending that meet the criteria of regulatory NBR 6118/2014 (design of concrete structures - Procedure) and application of the practice table in commercial building project. Table practice of beams in reinforced concrete, facilitates the design and detailing of beams under review.
