The presence of supplementary reinforcement, in the form of edge reinforcement and stirrups, has a significant influence on the load‐bearing capacity of anchorage groups with multiple anchor rows loaded in shear perpendicular to the edge. The current models available in the codes and standards are conservative for low to medium amounts of supplementary reinforcement but tend to be unsafe for high amounts of reinforcement. This paper presents the results of a comprehensive test program carried out to investigate the behavior of anchor groups with supplementary reinforcement loaded in shear toward the edge. The test results are discussed in detail to highlight the influence of supplementary reinforcement on the load‐bearing capacity of the anchorages. Based on the evaluation of these test results, a realistic and rational model has been developed to predict concrete edge failure loads for anchorages with supplementary reinforcement that will be presented in another paper.
