To investigate the similarities and differences of mechanical behavior between the bamboo-concrete connections and the wood-concrete connections, thirty-six specimens were tested through push-out tests with the material type (bamboo or wood), concrete strength and dowel diameter as test parameters. In addition to the linear variable displacement transducer the digital image correlation was also used to obtain the slip distribution of the whole field of the specimens, which was conducive to the further detailed analysis of the slip distribution and a comprehensive understanding of the load-slip relationship. The results showed that the failure modes of the bamboo-concrete connections were similar to that of the wood-concrete connections, such as the concrete failure near the joint and the dowels bending in different degrees. The load-slip curves of the two kinds of connections were similar, which could be summarized as the elastic section, strengthening section and descending section. The shear stiffness and capacity of bamboo-concrete connections were higher than that of wood-concrete connections, and the shear capacity increased with the increase of dowel diameter and concrete strength. The slip distribution of the left and right sides of the specimen was basically identical. The load-transfer performance of the dowel was excellent. Finally, the prediction method of shear capacity and load-slip curve model of composite connections were proposed and verified to be effective.

为了研究竹-混凝土连接和木-混凝土连接之间的机械性能的异同，通过推拉试验测试了36个样品，材料类型（竹或木），混凝土强度和木钉直径参数。除了线性可变位移传感器外，数字图像相关性还用于获得标本整个场的滑移分布，这有助于对滑移分布进行更详细的分析并全面了解载荷-滑移关系。结果表明，竹-混凝土连接的破坏模式与木-混凝土连接的破坏模式相似，例如节理附近的混凝土破坏和销钉的弯曲程度不同。两种连接的荷载-滑移曲线相似，可以概括为弹性截面，加强截面和下降截面。竹-混凝土连接的抗剪刚度和抗剪承载力高于木-混凝土连接，抗剪承载力随着销钉直径和混凝土强度的增加而增加。样品的左侧和右侧的滑移分布基本相同。定位销的载荷传递性能非常好。最后，提出了复合材料连接件的抗剪承载力预测及荷载滑移曲线模型，并验证了该方法的有效性。竹-混凝土连接的抗剪刚度和抗剪承载力高于木-混凝土连接，抗剪承载力随着销钉直径和混凝土强度的增加而增加。样品的左侧和右侧的滑移分布基本相同。定位销的载荷传递性能非常好。最后，提出了复合材料连接件的抗剪承载力预测及荷载滑移曲线模型，并验证了该方法的有效性。竹-混凝土连接的抗剪刚度和抗剪承载力高于木-混凝土连接，抗剪承载力随着销钉直径和混凝土强度的增加而增加。样品的左侧和右侧的滑移分布基本相同。定位销的载荷传递性能非常好。最后，提出了复合材料连接件的抗剪承载力预测及荷载滑移曲线模型，并验证了该方法的有效性。
