Influence of growth rate in density and mechanical properties of sawn timber
Mechanical quality of structural timber (50 mm x 150 mm x 3200 mm) is assessed by means of growth rates in different softwoods (P. radiata, P. pinaster, P. sylvestris), most of them fast growing species, and hardwoods (Populus sp. and Eucalyptus globulus) growing in Spain. The utility of using average density instead of growth rate is also assessed. Growth rate did not appreciably influence the density and bending properties of timber, and so its utility of prediction of mechanical quality of timber is very low.
