摘要

本文对钢筋混凝土(STC)节点在往复荷载作用下的性能进行了试验研究。对钢筋混凝土(RC)梁与钢-钢筋混凝土柱组成的5个组合节点试件进行了破坏试验。观察到三种失效模式。它们分别是:(1)梁的弯曲破坏;(2)梁的弯剪破坏;(3)梁和节点的剪切破坏。试验结果表明，钢筋混凝土节点的能量吸收能力取决于破坏模式和施加在柱上的轴向荷载水平。后者也影响节理的抗剪能力。

Experimental Study on Behavior of Steel-Reinforced Concrete Joints

The paper presents an experimental study on the performance of steel-reinforced concrete (STC) joints under reversal cyclic loads. Five composite joint specimens comprising built-up steel-reinforced concrete columns connecting to reinforced concrete (RC) beams were tested to failure. Three modes of failure were observed. They are: (1) bending failure in beam, (2) bending-shear failure in beam and (3) shear failure in beam and joint. Test results indicated that energy absorption capacity of the SRC joint depends on the modes of failure as well as the levels of axial load imposed on the column. The latter also influences the shear capacity of the joint.
