Abstract:
Results from two studies of headed reinforcement have been combined to develop design recommendations for headed reinforcement. Important aspects of headed bar anchorage are summarized, and a model for determining the anchorage capacity of headed reinforcement is presented. The model includes two components that contribute to the total bar stress, head bearing, and bond, each calculated separately. The proposed model is compared to data from previous headed bar studies. Proper use of the model and areas for additional study are discussed.
