| 摘 要： | 进行了 18榀不同配筋率和接缝宽度装配式钢筋混凝土结构试件在低周反复荷载作用下受力过程和破坏特性的试验研究及分析对比。研究表明 :试件在接缝处均发生了剪切破坏 ,接合筋“压力 -摩擦”抗剪力作用随配筋率的增加明显提高以及接缝宽度变化对抗剪强度的影响呈非线性关系。结合试验结果 ,建立了装配式钢筋混凝土结构竖向齿槽接缝极限抗剪强度的计算公式 ,建议公式与试验结果吻合较好 ,为进行工程设计提供了可借鉴的依据 |
| 关 键 词： | 装配式钢筋混凝土结构 低周反复荷载 竖向齿槽接缝 受力性能 |

| Abstract: | Experimental research and analysis comparison of force bearing process and failure behavior of 18 PRCA with vertical joint composed of dowel and alveolus specimens that were different in reinforcing bar ratio and joint width loaded by low cyclic repeated were achieved. The research showed that each specimen occured shear failure. And the authors obtained “compression friction” shear action raised with increasing reinforcing bar ratio and effect of change of joint width on shear strength of concrete showed nonlinear. Based on test results and theoretical analysis, a suggestion on calculating ultimate shear strength was proposed. It showed that the calculating results were in good agreement with the test ones and so the suggestion may be used in engineering design. |
