O objetivo desse trabalho foi desenvolver um sistema de cobertura metálica padronizado e modular, utilizando perfis tubulares laminados sem costura. Esse sistema se destina, principalmente, a coberturas de supermercados, shoppings etc., que necessitam de grandes áreas livres. Para se avaliar o comportamento estrutural desse sistema, foi construído, de maneira inédita no Brasil, um protótipo de 900 m², para testar o sistema construtivo idealizado e realizar ensaios com os carregamentos reais, nesse tipo de estrutura. Avaliando-se, então, o comportamento global da estrutura, com base em todos os resultados numéricos e experimentais obtidos, confirmou-se o comportamento previsto, no cálculo computacional, com o protótipo ensaiado. The purpose of this study is the comparison between experimental and numerical data of a roof system made of tubular steel sections. Such roof system is applied mainly for supermarkets, large stores and industries. To evaluate the structural behavior of this system, a 900m² prototype was built, - an unprecedented opportunity in Brazil to accomplish experimental tests with usual loads for this type of structure. Evaluating the behavior of the entire structure, with all the results obtained on experimental tests and numerical analysis, it was concluded that the prototype is in general accordance with the designed model in terms of stresses and displacement
