反复荷载下梁柱偏心节点粘结性能的试验研究

Experimental study of the bond behavior of eccentric beam-column joints under cyclic reverse loading

文章主要探讨了不同的加荷方式对钢筋混凝土节点粘结性能的影响,分析了单向加荷与反复荷载两种不同加荷方式下,钢筋混凝土节点的粘结机理,并通过钢筋混凝土梁柱偏心节点试件在反复荷载下,通裂阶段梁纵筋应力试验结果与理论计算数据进行分析比较,得出了反复荷载下钢筋混凝土节点粘结性能退化的规律,并提出了一些有益的建议。

The effect of different loading mode on the bond behavior of joints in the reinforced concrete is investigated,and the bond mechanism of the reinforced concrete joints under unilateral loading or cyclic reverse loading are studied. The stress of longitudinal steel bars of reinforced concrete eccentric beamcolumn joints in splitting phase, which were tested under cyclic reverse loading,is computed and analyzed. By comparing the experimental results with the theoretical calculations, the regularity of bond degradation is obtained.
