| Research Abstract |
In this research, we developed a high strength joint method for construction use of log timber, especially for Japanese cedar wood which has sufficient amount of accumulation in the forest and have demanded useful way of utilization. The improvement of mechanical property was studied by compressed wood technique. As a result we introduced formulas to express the various improved strength property of compressed wood and evaluated their dimension stability characteristic. In addition we developed the end connection using pipe and drift-pin for log timber and it achieved sufficient strength property.
