Bow ties subjected to tensile forces

Summary

In the first part of this paper, the main results from a series of experiments focused on the tensile performance of bow ties are presented. Eleven specimens using two different geometries were tested to evaluate their capacity and stiffness. Specimens showed a main failure mode: a combination between shear and compression failure in the contact area between the bow tie and the surrounding panel. In the second part, an analytical model to calculate the capacity according to Eurocode 5 is provided. Results show that the model overestimates by around 30\% the capacity observed in the experiments due to the deformation of the panel surrounding the bow tie: such deformation in fact reduces the contact area between the elements.
