Assessing the bearing capacity of Crestbond shear connectors to concrete pry-out

Abstract In this work, a study on failure by concrete pry-out in Crestbond shear connectors is presented. The study’s aim was the development of an expression that estimates connection’s bearing capacity. analyses were carried out through numerical simulations designed to reproduce referred mode. Numerical and experimental results are compared discussed relation maximum force reached cracking aspect typical pry-out. proposed equation corresponded well results, with mean ratio Ptheo/Pexp equal 0,99 coefficient variation 10%. found indicate German Technical Approval Z-26.4-56 can also be applied connectors.
