Analysis of angle type shear connectors in steel and concrete composite beams

Because there is no standardized calculation formula for angle-type connectors and they can be used in steel and concrete composite beams, this work aimed to analyze the shear resistance of 3mm vertically welded angle profiles with two different types of orientations. For this, 14 test specimens wer...

For this, 14 test specimens were made, 7 containing connectors with 45° orientations and another seven at 90°; these test specimens were subjected to push-out tests, obtaining load-slip data, which were treated statistically to be later used in behavior analysis of the connectors. Parameters such as strength, ductility, rigidity, and failure modes were analyzed. The failure mode that prevailed in all the test tubes was the fractionation in the entire width of the concrete; in terms of ductility, connectors with a 45° orientation are considered malleable according to the Eurocode. In addition, the characteristic stiffness is greater for connectors with a 90° orientation; These parameters were compared in both types of connectors, and it was concluded that those with a 90° orientation have higher resistance. Therefore, they are the most suitable for use in construction. Partiendo del hecho de que no se cuenta con una fórmula de cálculo normalizada para conectores tipo ángulo y que pueden ser usados en vigas compuestas de acero y hormigón, este trabajo tuvo como objetivo analizar la resistencia a corte de perfiles angulares de 3mm soldados verticalmente, con dos tipos de orientaciones diferentes. Para esto se elaboraron 14 probetas, 7 contenían conectores con orientación a 45° y otras 7 a 90°, dichas probetas fueron sometidas a ensayos push out obteniéndose datos de carga-deslizamiento los que fueron tratados estadísticamente para posteriormente ser usados en el análisis del comportamiento de los conectores. Se analizaron parámetros como la resistencia, ductilidad, rigidez y modos de falla, el modo de falla que predominó en todas las probetas fue el fraccionamiento en todo su ancho del hormigón; en cuanto a ductilidad, los conectores con orientación a 45° son considerados dúctiles según el Eurocódigo; además, la rigidez característica es mayor para los conectores con orientación a 90°; se comparó estos parámetros en ambos tipos de conectores y se concluyó que los que tenían una orientación de 90° tienen una mayor resistencia, por lo tanto, son los más idóneos para su uso en la construcción.
