| Abstract: | This paper reports the test of 27 specimens, of reinforcd concrete members with flexure and axial force.We have studied the effects of the ratio between the axial force and the compression strangtb, of concrete, the shear to span rafio as well as the ratio of longitudinal reinforcement on the behaviour of the plastic hinge. Formulas for calculating the yield and ultimate curvature of section, the angle of the platic hil~ge rotation as well as the equivalent length of the plastic hinge are given. Calculated results are in good agreemertt with the measured results. |
