Análisis experimental y comparativo de la resistencia a corte de conectores tipo ángulo con diferentes posiciones y su comportamiento en la unión de losas tipo deck sobre viga metálica.

Abstract

The approach of this research is technical experimental, the methodology that supports the study of angle connectors with different orientations in composite systems in the Push Out tests is standardized in the Eurocode 4, 16 specimens divided into groups of 4 were used, 8 specimens with a 3 mm thick connector and 8 specimens with a 4 mm thick connector, each group of 8 specimens are divided into two groups of 4 specimens, which differ from each other by the orientation of the connector at 45° and 90°, one specimen was taken from each group to perform the monotonic test. The transfer of shear forces between the concrete slab and the steel beam was analyzed, taking into account not only the mechanical properties of the materials used in the construction of the specimens, but also the construction process and the regulations for the reinforcement of the specimens. The results obtained are validated by comparing them with regulations and studies carried out by other authors in investigations with similar characteristics, it was evidenced that the failure mode was related to the geometry of the specimens leading to a premature failure of the concrete in the inner rib of the specimens, this effect was counteracted with the use of a reinforced lateral bracing that prevented sudden sliding and early completion of the Push Out tests.
