Abstract

In literature, one can usually find experimental investigations into global mechanical behaviour of soft-wood specimens, but properties of their individual components, (namely the properties of the late-wood and the early-wood parts) are rarely presented. Therefore, information on the moisture content and on the density is presented here. In fact, the ratio of the early- and late-wood parts in the cross-sectional area represents a significant influential factor, especially in the case of soft-wood components. Based on previous experimental data bases, the authors offer an original and simple analytical method for establishing Poisson’s ratios for new, untested soft-wood specimens.
