Tensile resistance of steel-reinforced anchorages: Experimental evaluation

One of the research topics related to composite steel-concrete structures is the connection between steel and concrete members-namely, the design of the anchorages. Because the design of steel-reinforced anchorages using the available methodologies (namely, from the CEB Design Guide, CEN/TS 1992-4, and ACI 318-08) may lead to excessively conservative results, experimental studies were conducted at the Civil Engineering Department of the University of Coimbra dealing with cast-in-place headed anchors. The aim of this study is the evaluation of the effect of hanger reinforcement on the behavior of steel-headed anchors embedded in concrete subjected to tension loads. A total of 40 laboratory tests, divided into two groups, were performed, dealing with plain concrete; hanger and usual grid surface reinforcement; and the variation of the member thickness, embedment depth, and proximity of the concrete member edges. Some conclusions from the tests are analyzed and discussed.
