Concrete cone breakout behavior of anchor groups in uncracked concrete under displacement-controlled cyclic tension load
Highlights Displacement-controlled cyclic loading of anchor groups. Experimental investigation on the displacement and hysteretic behavior. Comparison of the behavior of anchor groups under static and cyclic loading. Behavior of various anchor configurations and influence of eccentric loading. Performance of individual anchors of the group.
Abstract Post-installed anchors can offer a low-invasive and practical solution to connect strengthening elements with the existing reinforced concrete structure in seismic retrofitting applications. Such a connection formed with multiple-anchor groups is faced with several challenges due to high demands and structural or architectural features. In the framework of a performance based design, the displacement and hysteretic behavior is more important than the forces acting on the anchor groups. In this context, the primary aim of this work is to investigate the performance of anchor groups under static and cyclic tension load with emphasis on the behavior of different geometric anchor configurations, concentric loading, eccentric loading, and the behavior of the individual anchors within the group. Tests were conducted on single anchors and anchor groups under static and displacement-controlled cyclic loading. The experimental program, experimental setup are described, and the experimental results are presented and discussed in detail in this paper.
