Bond-Slip Relationship of Beam Flexural Bars in Interior Beam-Column Joints
Under cyclic loading, the structural performance of reinforced concrete beam-column connections is significantly affected by the bond slip of beam flexural bars. In this present study, a bondslip model was developed to evaluate the bond slip of beam flexural bars within beam-column joints using simplified bond strength and bar strain. To address the cyclic loading effect, the bond strength was determined from the existing test results of beam-column connections that showed complete bond failure. For verification, the predictions of the proposed model were compared with the existing test results of concrete block specimens and beam-column joint specimens. The results showed that the proposed model predicted the bond strength degradation and bond-slip relationships with reasonable precision. For performance-based design, a bond requirement was proposed as the function of the ductility demand of beam-column joints.
