The application of headed bar as an anchorage in the concrete structure is increasingly popular. Headed bar become a solution to solve the congestion problem, simpler installation, reduction in steel used, and potentially shorter anchorage or embedded lengths at the beam-column joint. There is already some design code for headed bar based on various failure modes. However, the limitation of the fc' and fy value on those design codes are in the range of normal strength value. Therefore, this study is conducted to find the behavior of the headed bar embedded in the high-strength concrete.
This research will start with the comparison or parametric study of several anchorage capacity equations which based on various failure mode to find out which failure mode is critical in the high strength beam-column joint. This research is using typical exterior beam-column joint as the study case. After identifying the failure mode, this research comes with side-face blowout failure mode as the most dangerous failure mode, and thus the total of 81 specimen data that is assessed using ANSYS, although only 12 specimen data that is constructed.
Side-face blowout and yield of the steel bar are the critical failure mode to high-strength beam-column joint with headed bar as the anchorage. Based on the ANSYS results, the effect of the variable fc', fy, db,and C to anchorage capacity of the joint can be known. Chun (2017) capacity equation also doing a good job to predict the side-face blowout failure which is analyzed by ANSYS.
