Resumo
This 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.
