چکیده انگلیسی


• An experimental program that investigates the behavior of an innovative technology for connections.
• Two stages of tests in order to validate the best test setup.
• A satisfactory behavior of the proposed connection in terms of strength.

This paper presents the results of an experimental program developed to investigate the behavior of an innovative technology for connections by adhesion, interlocking and friction in composite structures. Connections have a strategic importance for precast concrete and steel–concrete composite structures, since they determine the global structural behavior and affect the whole production process, from execution to assemblage and other services on site. Currently, however, steel–concrete composite connections are not completely adapted for their use in prefabricated slabs. In this way, the development of new types of connections is clearly necessary, where connections by adherence (or connections by adhesion, interlocking and friction) seem quite promising. To improve the knowledge in the field of connections by adherence, this paper proposes a new geometry of embossments in the steel and in the concrete surfaces associated with the use of a high performance mortar. Monotonic push-out tests are performed, and their results are presented and discussed. A satisfactory behavior of the proposed connection in terms of strength is observed, justifying further studies on the subject.
