Fourteen subassemblage frame tests have already been carried out to investigate the load carrying capacity and ductility of beam-column joints with mechanical anchorages. The proposed equations on mechanical anchorage capacities are also verified in these tests. The load carrying capacity and ductility of beam-column joints with mechanical anchorages under three failure types (flexural yielding of a beam, shear failure of a joint, and side splitting failure of concrete cover around anchorage) are discussed by comparing with those with 90-deg. hooked bar anchorages based on frame test results. The physical performance of mechanical anchorages is approximately equal to that of 90-deg. hooked bar anchorages.
