低周反复荷载下钢筋混凝土框架边节点抗剪强度的试验研究

Shear Strength of Exterior Joints ot Reinforced Concrete Frames Subjected to Low Cyclic Loading

本文介绍五个钢筋混凝土框架过节点试件在低周反复荷载下的试验结果。对边节点的抗剪强度进行了讨论。在与混凝土结构设计规范送审稿中框架节点抗剪强度计算公式对比的基础上,提出了框架边节点抗剪强度计算建议,对比试验结果,符合较好。

With test results of five specimens of exterior joints of rein- forced concrete frames subjected to low cyclic loading, the shear strength of these joints is discussed. On the basis of comparison with the formulas suggested by reinforced concrete structure design code, a method of calculating the shear strength of exterior joints of frames is proposed. The calculated data are compared with the test results and are comparatively satisfied.
