The behavior of anchor groups arranged parallel to the concrete edge in one single anchor row and loaded in shear perpendicular to the concrete edge is experimentally investigated. A comprehensive test program was performed to obtain information on the group behavior, the influence of the displacement behavior of single anchors, influence of load eccentricity, and influence of crack pattern. A special configuration with unequal edge distance was also tested. The results showed that the anchorage behavior is highly dependent on the load-displacement behavior and on the stiffness conditions of the individual anchors within the group. It would be reasonable to consider the volume of activated concrete to consider different concrete geometries. The test results are aimed to generate a test database and are used to develop a new analytical model for the concrete edge failure mode of shear loaded anchor groups that will be presented in a future paper.
