Abstract
The evolution of concrete is enabling the production of slender reinforced concrete components with the application of thin rebars. Although there are many studies related to the steel-concrete bond, a specific standard for bond tests of thin rebars is still missing. This paper presents some questions about methodologies for bond tests and the geometry of pull-out test specimens. This paper also presents bond coefficient (ηb) values for thin rebars. An experimental programme was performed for this purpose. The results showed that cylindrical specimens in pull-out tests presented bond-strength values closer to bond-strength values from beam tests. A test methodology adopting cylindrical specimens is suggested.
