Laboratory of Engineered Timber and Joints

Engineered Timber and Joints Laboratory was carried out in 2001 in April, ｊoining two research laboratory, was born by an independent administrative institution of the Forestry and Forest Products Research Institute.

Materials and performance laboratory were studying the strength of the wood around the lumber, the mother is a joint laboratory that was doing research of the junction which is indispensable in order to create a structure of wood.

The laboratory of Engineered Timber Joints (ETJ: but that is called Timber Jointing Laboratory; offically) was established in october in 1988 when the Forestry and Forest Products Research Institute (FFPRI) was largely re-organized. The origin of ETJ was the Laboratory of Industrial Application of Wood Products where the timber joints had been studied before then. The research range of ETJ is everything which is wedding timber mechanically and also relates joints and connections in timber construction.

We are mainly researching on joints of timber structure made by axial members and its structural performance.
