First check Table 2.1 - List of Sawn Lumber Species Combinations beginning on page 4 of the NDS Supplement
. Design values for the species listed in the NDS Supplement
are provided by the grading agencies.
The 2005 NDS supplement
(and subsequent editions) Table 4F has non-North American visually graded dimension lumber including:
Austrian Spruce - Austria and the Czech Republic
Douglas Fir/European Larch - Austria, Czech Republic, Bavaria (Germany)
Montane Pine - South Africa
Norway Spruce - Estonia, Lithuania, Finland, Germany, NE France, Switzerland, Romania, Ukraine, Sweden
Scots Pine - Austria, Czech Republic, Romania, Ukraine, Estonia, Lithuania, Finland, Germany, Sweden
Silver Fir - Germany, NE France, Switzerland
Southern Pine - Misiones Argentina
As for other foreign species such as mahogany, ipe, greenheart, etc., or domestic species such as ash, locust, magnolia, walnut, etc., there is some design information in the Wood Handbook
published by the US Dept of Agriculture Forest Service, which can be found at http://www.fpl.fs.fed.us
. However, since these values are average unadjusted ultimate values, they need to be adjusted per applicable ASTM standards, such as ASTM D245, to arrive at allowable properties. A further complication is that if lumber is not grade stamped in accordance with American Lumber Standard Committee (ALSC) rules:http://www.alsc.org/
, there is no way of knowing what type of product will be used in construction. Engineering judgment will be required to use these types of foreign species in structural applications.
