000010451 520__ $$2eng$$aNew ACI 318-08 provisions for headed deformed bars (§12.6) detail the development of headed deformed bars and mechanical anchorage of reinforcement, such as development length, maximum allowable concrete strength, bar and head size, as well as side cover and clear bar spacing. However, the restriction of §12.6.1(f) hinders use of headed bars for the case where bar clear spacing is less than 4db, which is in fact common for beam or column reinforcement of moment frames. Given this conflict, the need exists to provide guidelines to supplement ACI 318-08, particularly for headed bars terminating in beam-column joints of frames. For these, all the existing data concerning headed bars (a total of 91 beam-column joint specimens) have been complied and re-assessed. As well, all available ACI standards have been reviewed and discussed. Finally, this study documents all these test results in a uniform format and provides a detailed review of the data needed to update ACI 352R-02 recommendations on the design of beam-column joints with headed bars.
