timber rivets and the nds...
good afternoon.
the following is the definition of pw for timber rivets, according to the 2001 nds, section 13.2.1 (pg 116-117):
"pw = tabulated nominal wood capacity design values parallel to grain (tables 13.2.1.a-13.2.1.f) using wood member thickness for the member dimensions in tables 13.2.1.a-13.2.1.f for connections with steel plates on opposite sides; and twice the wood member thickness for the member dimensions in tables 13.2.1.a-13.2.1.f for connections having only one plate, lbs."
by this definition, one might assume that if the connnection had a steel plate on only one side (face) of the members being connected, one would enter the tables and reference values listed for a tabulated member which was twice the actual member thickness... which seems very, very counterintuitive, anyway.
now, throw in the following blurb from the nds commentary (1997 and 2001; nearly identical), and things really seem to get all confused:
"... pw values tabulated in nds tables 13.2.1.a through 13.2.1.f apply to connections made with 1/4" side plates and to one plate with associated rivets... where connections involve plates on two sides of the wood member the... applicable tabular pw value is doubled to determine the reference capacity of the connection."
man, oh man... i can't really tell for sure, but it seems like the commentary language reads exactly the opposite of the actual specification language...?!!   spec says, 鈥溾
