Skin timber can be defined as hollow timber that is circular or rectangular in cross section with an inner cavity whose cross-sectional area is more than 90% of the total cross section. Using small samples instead of full-scale skin timber, we examined the different failure types and the strength properties of bored and non-bored specimen. From these results, we prepared strength estimates as a function of the boring diameter. Adding wood density as a second independent variable, we were able to estimate the strength properties more accurately. We conclude that it will be important to perform similar measurements and regression analyses for full-scale skin timber is need, and development of hybrid structure using skin timber which can complements the strength loss of it due to its boring area is also required.
