Item Análise experimental da resistência à flexão simples de vigas de aço tipo "I" compostas de perfis laminados dotadas de mendas soldadas(Ricardo Prado Abreu Reis, 2016-02-02) Borges, Rone Sergio Freitas; Gomes, Orlando FerreiraThis paper presents the experimental study of bearing capacity of bi supported by steel beams made of rolled section I of type W 250 x 22.3 ASTM A572 grade 50 profiles rolled parallel tabs with two axes of symmetry, being endowed with amendments with full penetration welds of type MIG (Metal Inert Gas). Seven beams were tested with a length of 3000 mm, with a reference beam. In the remaining six beams amendments were made in different positions varying the amount of amendments. Furthermore, it is a comparison with the behavior of beams with bolt seams studied by Pereira (2014), in which beams used with the same provisions of seams used in this work, but with ASTM A325 and screw diameter of 19 mm. All models were subjected to simple bending stress at break, in which the vertical displacements were measured relative displacements and specific torsional deformations steel. The links of beams resisted the simple bending tests, not being detected no break in welds and even the screws. The main contribution of this work was to show that the beams with welded and bolted connections with the specifications described in this paper can be used as structural elements, as well resisted the efforts required.Item Ligações em estruturas de aço utilizando emendas com parafusos de alta resistência solicitadas na flexão simples(Ricardo Prado Abreu Reis, 2014-04) Pereira, Ronivon; Gomes, Orlano FerreiraStructure is designed to have satisfactory performance given the quality standards and requirements in the construction of which designers need. Increasingly, large metal structures are developing in this competitive market, where performance and quality of the project depend on manufacturing processes of materials, assembly, inspection and maintenance. The metal structures, especially those of type I profiles of parallel laminated tabs depend on the quality control in your bolted splices. This article aims to analyze the bearing capacity of steel beams supported by profiles consist of type I rolled parallel flanges with two axes of symmetry, being endowed with seams with high strength bolts type ASTM A325, diameter 19 mm, being requested by models of simple bending efforts.Item Ligações em estruturas de aço utilizando emendas com parafusos de alta resistência solicitadas na flexão simples(Ricardo Prado Abreu Reis, 2014-05-22) Pereira, Ronivon Soares; Gomes, Orlano FerreiraStructure is designed to have satisfactory performance given the quality standards and requirements in the construction of which designers need.
