Wood Dowels embedded in concrete

[Subject Prev][Subject Next][Thread Prev][Thread Next]
NDS Table 11E is for single shear sawn lumber bolted to concrete with an embedment of 6" or greater.  For a case with less than 6" embedment, is there some sort of an adjustment factor to determine the capacity?  For a paltry couple hundred pounds of loading, is a 6" embedment any different than a 3" or 4" embedment?
 
Or is it perhaps acceptable to use either Table 11J for lag screws or Table 11A for bolts, hopefully as a conservative backup?  Table 11A would be a much better value, but then what would be the thickness for the main member?  It might be reasonable to use a large thickness for the main member to better model the concrete, but that might be a real stretch.
