Development of New Connecting Method in Timber Structure for Re-used Member Obtained from Dismantling

为了减轻接头重量并提高木材的回收利用率，我们开发了木质连接器作为金属连接器的替代品。断裂模量为500 MPa，可以通过使用致密化技术获得。然而，它已被观察到，木连接器是容易脆性断裂相比，钢连接器，这已被确定为一个问题，我们讨论的可能性，通过使用竹剪切板连接器的木材，以提高木结构的节点的延性。我们已经成功地获得了更高的延性使用致密竹棒剪切板。通过节点加载试验，研究了竹杆剪力板厚度和直径对节点受力性能的影响。

To reduce joint weight and improve recycling of wood, we developed wood-based connectors as a substitute for metal connectors, A high-strength wood-based material, e.g., modulus of rupture of 500 MPa, could be obtained by using the densification technique. However, it has been observed that wooden connectors are susceptible to brittle fractures as compared to steel connectors ; this has been identified as a problem.We discuss the possibility of enhancing the ductility of joints of timber structures by using the wood of bamboo shear plate connector. We have succeeded in obtaining higher ductility using the densified bamboo stick shear plate. The loading test of joint is carried out to research the effect of the thickness and diameter of the bamboo stick shear plate on the mechanical behavior of joint.
