[Subject Prev][Subject Next][Thread Prev][Thread Next]

You are correct, but the chord tension forces are generally small enough to
be resisted by a butt splice weld.  And it should be detailed.

Most of these angles come in 10 feet lengths and are not spliced unless
detailed that way. If they are not spliced then you cannot count on them to
resist chord forces.
