Resumo
Structure 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 study aimed 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. Eight beams with a length of 3000 mm, two reference beams were tested. In the
remaining six beams splices were made at different positions varying the amount of seams.
All models have been efforts required by simple bending to failure, by analyzing the vertical
displacement, torsional displacement relative and specific deformations of steel. The
connections of the beams withstood the test flexural not being observed and no break on the
bolts or the connecting plate, featuring breaking loads between 74% and 85% for beams of
series with connections. Considerably beams with connections showed no breaking loads far
below the reference beams with breaking loads between 78% and 100%. The results indicate
that the beams with bolted with high strength bolts connections are sturdy and therefore can
be used by designers in the field of steel structure as another option.
