| Research Abstract |
In recent year, for rubbish disposal and waste problem, the segregation of wood and the metal were difficult problem. The problem will be solved to use the wood based connector such as densified wood connector instead of metal connector at joints in timber structures. In this study, the densified technique of sugi was adopted. The usage of densified sugi leads to improve recycling rate because the segregation of metal is not necessary. The strength characteristics of the keyed mortise and tenon connection with key made from densified sugi were unveiled by the tension test of joint. From the test results, the key made of 70% densified ratio without steam treatment was suitable for keyed mortise and tenon connection.
