Experimental study of angle type shear connectors in position L and V embedded in composite slabs with steel decks
This article presents a study of angle-type shear connectors, as a new proposal for a monolithic work of the composite slab system with collaborating sheet, considering that there are currently no regulations that validate its use. The experimental analysis of 14 specimens with angle-type shear conn...

The experimental analysis of 14 specimens with angle-type shear connectors positioned in plan at 90º (type L) and 45º (type V), tested with the Push-Out method established by Eurocode 4, is presented. Mechanical properties such as shear strength, ductility, and stiffness as a function of connector position, as well as failure mode. The results showed that the two groups of specimens have similar shear strength and ductility, differentiating between V-type connectors with a stiffness value 42% higher than differentiating between V-type connectors with a stiffness value those obtained in L-type connectors. The typical failure mode is due to premature cracking, of the concrete in the cross section of the slab.

Se presenta el análisis experimental de 14 probetas con conectores de corte tipo ángulo posicionados en planta a 90º (tipo L) y 45º (tipo V), ensayados con el método Push-Out dispuesto por el Eurocódigo 4. Se obtienen las propiedades mecánicas como la resistencia a corte, ductilidad y rigidez en función de la posición del conector, además del modo de falla. Los resultados demostraron que los dos grupos de probetas presentan resistencia a corte y ductilidad similares, diferenciándose los conectores tipo V con un valor de rigidez superior en 42% a los obtenidos en conectores tipo L. El modo de falla típico se presenta por un agrietamiento prematuro del hormigón en la sección transversal de la losa. Los resultados obtenidos de capacidad a corte son comparados con algunas expresiones empíricas de normativas internacionales y estudios previos de conectores similares Universidad Centroccidental Lisandro Alvarado - Decanato de Ingeniería Civil 2022-07-31 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo científico de investigación original application/pdf https://revistas.uclave.org/index.php/gt/article/view/4063 10.51372/gacetatecnica232.6 Gaceta Técnica; Vol. 23 No. 2 (2022): July-December; 70-87 Gaceta Técnica; Vol. 23 Núm. 2 (2022): Julio-Diciembre; 70-87 Gaceta Técnica; v. 23 n. 2 (2022): July-December; 70-87 2477-9539 spa https://revistas.uclave.org/index.php/gt/article/view/4063/2627 https://revistas.uclave.org/index.php/gt/article/view/4063/2628 https://revistas.uclave.org/index.php/gt/article/view/4063/2629 https://creativecommons.org/licenses/by-nc-sa/4.0 |

This article presents a study of angle-type shear connectors, as a new proposal for a monolithic work of the composite slab system with collaborating sheet, considering that there are currently no regulations that validate its use. The experimental analysis of 14 specimens with angle-type shear connectors positioned in plan at 90º (type L) and 45º (type V), tested with the Push-Out method established by Eurocode 4, is presented. Mechanical properties such as shear strength, ductility, and stiffness as a function of connector position, as well as failure mode. The results showed that the two groups of specimens have similar shear strength and ductility, differentiating between V-type connectors with a stiffness value 42% higher than differentiating between V-type connectors with a stiffness value those obtained in L-type connectors. The typical failure mode is due to premature cracking, of the concrete in the cross section of the slab. The results obtained for shear capacity are compared with some empirical expressions of international regulations and previous studies of similar connectors |
