Title: | Transfer of shear stresses at steel-concrete interface | Authors: | Chrzanowski, M. Odenbreit, C. Obiala, R. Bogdan, T. DEGEE, Herve |
Issue Date: | 2019 | Source: | Steel construction, 12(1), p. 44-54 | Abstract: | Shear stresses can be transferred via bond at the steel-concrete interface without having to consider any mechanical shear connectors. The research conducted shows that the use of anti-adhesive products, such as grease, reduce the bond at the steel-concrete interface in push-out tests (POTs). However, the effect is still significant, especially for fully encased steel profiles. The results of an experimental POT campaign with nine small-scale cube specimens and two composite column specimens are presented here. Three different surface conditions were examined: a) an untreated surface, b) a surface treated with anti-adhesive agent (formwork release oil) and c) a surface treated with PTFE spray. The resulting ultimate shear stresses were compared with the experimental results available in the literature [1–10]. How the different geometries of the specimens, the concrete age and the surface treatment conditions influence the bond strength are compared and summarized. | Keywords: | steel-concrete composite columns; composite action; longitudinal shear; steel-concrete bond; shear stresses between plain steel and concrete surfaces; assessment of steel-concrete bond strength; analysis of steel-concrete bond behaviour | Document URI: | http://hdl.handle.net/1942/27991 | ISSN: | 1867-0520 | e-ISSN: | 1867-0539 | DOI: | 10.1002/stco.201800024 | ISI #: | 000458113600006 | Rights: | Copyright Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.
