摘要
本文进行了27根钢筋混凝土压弯构件的试验,研究了轴压比、剪跨比和配筋率对塑性铰性能的影响,提出了钢筋混凝土压弯构件截面屈服曲率、极限曲率、塑性铰转角和塑性铰等效长度的计算公式,计算结果与试验结果符合良好。
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.
