Abstract(s)
As normas são documentos técnicos regulamentares, baseadas num conjunto de regras, requisitos, condições e especificações, produzidos com o fim de padronizar e orientar profissionais, de qualquer área do conhecimento, a conduzirem os seus trabalhos e serviços e, assim, assegurar a entrega de um produto final de maior qualidade possível para os utilizadores. No caso de lajes ou qualquer estrutura convencional de betão armado, existem normas diferentes em todo o mundo, mas com o mesmo objetivo, isto é, entregar estruturas de betão armado, atendendo as necessidades de qualidade, segurança e custo. Nesta dissertação, serão estudadas e analisadas duas normas importantes para dimensionamento de estruturas de betão: a Norma Brasileira 6118:2014 (NBR) e o a norma portuguesa NP EN 1992-1-1, proveniente do conjunto de normas europeias relativas a projetos de betão armado - Eurocódigo 2. Por se tratar de um tema bastante abrangente, esta dissertação foca-se apenas no estudo de lajes de betão armado maciças e fungiformes. A presente dissertação contempla uma revisão bibliográfica do tema e dos seus pormenores, utilizando as literaturas brasileira e portuguesa mais conhecidas. É feita a comparação dos seus conceitos, equações, coeficientes de segurança, valores característicos das ações e resistências, considerações gerais e peculiaridades de cada norma. Num segundo momento, haverá duas aplicações práticas das duas normas num mesmo modelo de laje e de acordo com certos princípios tradicionais de cálculo de cada país, com as devidas análises comparativas dos resultados em termos de esforços de cálculo, quantidade armaduras e altura das secções.
The norms are technical documents produced for the purpose to standardize and guide professionals in any field of knowledge and conduct your jobs and services with a certain level of quality and so deliver a final product suitable for the consumer. In general, the norms are a set of laws, standards, specifications that help the professional to direct your work to deliver a product of the highest possible quality. In the case of slabs or any conventional reinforced concrete structure, the situation is not very different, there are different norms all over the world, but with the same objective, to deliver reinforced concrete structures, supplying the needs of quality, safety and custody. In this dissertation, two important norms that address the subject about design of reinforced concrete structures: the Brazilian standard NBR 6118:2014 and the Portuguese standard NP EN 1992-1-1 from the set of European standards related to reinforced concrete projects called Eurocode 2. As this is a very comprehensive topic, this dissertation will have the main focus of development in the study of reinforced concrete slabs among its various types. The present dissertation will contemplate a bibliographic review of the theme and its details, using the most renowned Brazilian and Portuguese literatures, comparing its concepts, equations, coefficients, values, considerations and peculiarities of each. In a second step, there will be practical applications of the two standards in the same slab model with their due comparative analysis not only of the results, but also of the whole process itself until the end.
