    • Abstract
  • Determinations were implemented by non-destructive evaluation （NDE） methods, like transverse vibration （TV） and three-point static bending （TSB） on static and dynamic modulus of elasticity （MOE） of dimension lumbers of Spruce-Pine-Fir （SPF） of grade J imported form Canada. The results showed the MOE of SPF dimension lumber was normal distribution and one third of them had the MOE in the range from 10000MPa to 11000MPa. Mean dynamic and static MOE measured by TV and TSB was 10983MPa and 10523MPa. It had strong correlation between dynamic MOE and static MOE（R2=0.91）.
