A total of twelve pullout tests and two, full-scale, cyclic beam-column joint tests were carried out to examine pullout and seismic anchorage behavior of headed bars. The variables selected for pullout tests were the loading condition, the head type (size and shape), and the technique to attach the head to the bar end. The pullout test results revealed that all types of head sizes/shapes and head-attaching techniques achieved the proper anchorage under monotonic and repeated loads. The seismic tests indicated that both beam-column joints failed in a ductile manner, exhibiting similar patterns of cracking and the same level of lateral strength. The joint using headed bars showed better seismic performance in terms of the damage extent, lateral drift capacity and energy dissipation, compared with that using hooked bars. These experimental results demonstrate that headed bars with small heads (Abrg/Ab ≈ 2.6) could be used as an alternative to hooked bars for the design of exterior beam-column joints.
