Statistical analysis of mechanical properties of wood

It is a known fact that wood is a very good material for structural building components. This paper attempts to carry out a series of statistical analyses to show the relationship or correlation between different types of wood as relates to their different mechanical properties. An analytical method was used to calculate the values of the parameters, while some statistical concepts were adopted to find the relationship and correlation between them. Computer software– Maple, was used to draw the graphs. The results give some information useful for structural engineers in taking important decisions. Some of the striking results are that average stiffness of the American hardwoods, considered in this paper, is greater than average stiffness of the American softwoods, and there is a little positive correlation between the bending stiffness and the compressive stiffness of America hardwoods.
