Projeto executivo de pavimento com viga em concreto armado e concreto protendido

Abstract

The challenges of dimensioning and designing structures have become increasingly frequent today due to modern architectural arrangements. That said, with technological advancements and the development of more efficient building methods and materials, the field of concrete structures (the most conventional type) has been most impacted by these advances, as product design has forced a diversification of methods to deliver a safe and feasible project. In this sense, prestressed concrete is one of the methodologies that satisfies these needs, being applied to structural elements such as beams and slabs. As an example, the following study will address the conventional methods of dimensioning and calculating a reinforced concrete beam and, as a counterpoint, the same context will be adopted, but applying the prestressed concrete methodology, producing an executive project of both beams, with their respective quantities and indices. The results indicated a reduction in deflection when comparing the two methods making it possible to analyze the cost and benefit of adopting prestressed concrete in relation to reinforced concrete, making the project more or less expensive.
