To date, anchorage to concrete has received little attention in structural codes. Emphasis has been primarily on the tensile and shear capacities of anchorage devices. As designs became more sophisticated and analysis more exacting, more emphasis was placed on the transfer of loads through single anchors and anchor systems. It was recognized that performance of anchors controlled these load transfers, and that generally, failure modes at ultimate anchor capacities were important. There are no definitive design codes or anchorage performance criteria on which designers and installers could rely. First, this paper summarizes anchor types used for anchoring structural members to concrete. And second, failure modes and strengths characteristics of various anchor types are investigated. Finally, real field problems related to anchor failure are discussed in terms of failure modes and strength based on the analytical results.
