Abstract

The purpose of this study is to develop the mechanical anchorage, namely MAB-BOP (Mechanical Anchorage of 90$^{\circ}$ Hooked Bars with BOlt nad Plate) of the beam-column joint in precast concrete framed structures. Six specimens simulating typical interior beam-column joints were tested to investigate the mechanical characteristics of MAB-BOP. Of primary interest was the measurement of the slip of the anchored bar. Th load-slip curve obtained from this test were used to compare the mechanical performances of the different anchoring methods. Based on the test results, it was found that MAB-BOP showed sufficient anchoring strength capacity compared to 90$^{\circ}$ hooked bar method. So, MAB-BOP can be used as the anchoring methods of the reinforcing bars in PC beam-column joint.
