Dimensional lumber from Larix kaempferi, Larix gmelinii and Picea sitchensis were selected and jointed with domestic truss plates, respectively, to test joint failure, ultimate load carrying capacity and ductility of the jointed components. Testing results indicated that with loading parallel to wood grain, Larix gmelinii dimension lumber joints presented the highest ultimate load carrying capacity and the Picea sitchensis dimension lumber joints showed the lowest. Under loading vertical to wood grain, Larix kaempferi dimension lumber joints presented the highest ultimate load carrying capacity and Larix gmelinii dimension lumber joints showed the lowest.
