Experimental Behavior of Concrete Joint Interfaces under Reversed Cyclic Loading
Publication: Journal of Structural Engineering
Volume 134, Issue 9
Abstract
A large scale test on concrete joints subjected to constant compressive confinement and reverse cyclic shear load is performed. Shear strength, dilatancy degradation, and overall response are reported. A description of roughness as composed by two orders of asperities with different sizes is used to analyze the results and prompts the extension of an existing generalized joint model. The validity of the interpretation and the role of the proposed extension are pointed out by means of comparisons between numerical simulations and experimental results.

Acknowledgments
This work was largely made possible through the financial support of the Italian Ministry for University and Research (MIUR), which enabled the visit of the second writer to Milan Politecnico, along with the accompanying research fund. In addition, the first writer would like to acknowledge the support by MIUR through COFIN02 grant on “Concrete dam-foundation-reservoir systems: integrity assessments allowing for interactions.” The writers are particularly grateful to Antonio Cocco of the Structural Engineering Laboratories of Milan Politecnico for his help in carrying out the experimental tests.
