Evaluation of the variability of compressive strength parallel to the fibers of hardwood species

Abstract: Wood has several advantages as structural material. For this use to be applied in a safe way, it is necessary to know the statistical behavior of the mechanical properties. Some works and normative codes, such as the “Brazilian timber standard” (as well as its review pr...
