Wood design...
I have the timpber design manual (green one). It is based on the 1997 NDS. Pretty similar. Very good book, but why are the 1997 Fv values almost half of the 2001 Fv values? What changed between those two codes?
second question deals with flat use factor Cfu and Size factor CF. If you have a 2x6 being used on the flat (for some reason), you would use the flat use factor when calculating the allowable stresses. What about the shape factor? is the member 2" deep? 6"deep? or is the shape factor not used at all in conjunction with Cfu?
thanks :reading:
