thermal thermal conductivity of panels in perpendicular to the grain of main axis of nail strength in perpendicular to the grain direction was higher than that of parallel to the all wooden materials were conditioned at 20 c and 65 relative humidity why is wood so much stronger parallel to the grain than quora why is wood so much stronger parallel to the grain than perpendicular wood is in general strong and stiff when loaded parallel to grain, but relatively weak what are the adjustment factors to be done in design values their is always some variation in the design values calculated in timber. ch is the shear stress factor gt permitted for fvparallel to the grain for sawn lumber members. fc is the design value for compression perpendicular to the graindirect shear test on timber
