Project

Development of Large High-Strength Headed Reinforcing Bars

Research purpose

The proposed study will expand the available data on the anchorage strength of high- strength headed reinforcing bars to include the largest sizes currently permitted in the ACI Building Code, No. 14 and No. 18, and use those results to verify the applicability of the currently proposed design criteria and, if needed, formulate new design criteria to cover the larger bar sizes.
