Abstract(s)
As normas técnicas vieram como uma forma de padronização dos procedimentos de cálculo, de controle de qualidade dos materiais, de uniformização dos processos executivos e de segurança. Mais especificamente as normas de dimensionamento de estruturam promovem a padronização dos projetos de estruturas, visando a segurança, conforto e confiabilidade no produto final. Com o crescimento acelerado da construção civil no mundo, essas normas foram tomando uma maior importância e um maior aprimoramento, a fim de se manterem alinhadas as novas tecnologias. O concreto armado é a técnica mais utilizada em todo o mundo para a construção de estruturas, possibilitando a execução de diferentes elementos construtivos como vigas, pilares, pórticos, entre outros, sendo que esse sistema construtivo deve atender a norma local para o dimensionamento. Devido a distinção entre normas para diferentes locais, esse trabalho possui o intuito de comparar a norma vigente no Brasil para o dimensionamento de estruturas, NBR 6118:2014 e a norma europeia NP EN 1992-1-1. 2010 tomando como exemplo uma viga bi-apoiada de modo a criar uma comparação entre os materiais, a quantidade de armadura para cada sistema normativo e algumas disposições construtivas de cada uma das normas. Em relação aos resultados, foi verificado semelhanças para o dimensionamento a flexão de vigas. Já para o dimensionamento ao esforço transverso, houve uma considerável disparidade entre os valores de armadura transversal, assim como para a quantidade mínima de armadura.
Technical standards came as a standardization form of calculation procedures, materials quality control, and leveling of executive and security processes. More specifically, structural design standards promote the standardization of structural projects, aiming for safety, comfort and reliability in the final product. With the world’s quick growth of civil construction the standards have become more important and improved, in order to keep the new technologies aligned. Reinforced concrete is the most used technique for structures construction in the world, thus enabling the execution of different constructive elements such as beams, pillars, frames, among others, and considering that the construction system must meet the local sizing standard. Due to the distinction between standards for different locations, this work intends to compare the current standard in Brazil for the dimensioning of structures, NBR 6118:2014, and the European standard NP EN 1992-1-1 2010 by taking as an example a bi-supported beam. A comparison between the materials will be created, as well as the amount of reinforcement for each normative system and some constructive dispositions of each one of the norms. Regarding the results, similarities were verified for the dimensioning of the bending of beams. For the dimensioning of shear stress, there was a considerable disparity between the transverse reinforcement values, as well as the minimum amount of reinforcement.
