Analytical Investigation of Tension Loaded Deformed Rebar Anchors in Concrete

Experimental testing of deformed rebar anchors (DRAs) has not been performed extensively, so there is limited test data to understand their failure behavior. This study aims expand upon these tests and the behavior anchors, when loaded in tension. Analytical benchmark models were created using available a parametric was performed. Anchor diameter, spacing, embedment, number varied for total 49 concrete breakout simulations. The different modes predicted analytically, which showed that prominent DRA groups. values consistent with mean 5% fractile capacities determined from ACI capacity design (CCD) method. factor empirically simulation results kc = 26. value corresponds closely 24 specified 318-19 349-13 cast-in place anchors. analysis show CCD formula can be conservatively used DRAs tension by applying no greater than
