Subject: double bolt rows

We have found in our office that many times a double (or triple)
bolt row is required at steel beam connections that are part of
the collector system as these must be checked at omega level
forces. This would seem to produce a degree of rotational rigidity.
Does anyone know of an approach to use for determining the
moment induced by this rotational rigidity?
We have found an approach to addressing the rigidity issue for
a single bolt row in an old "Steel Tips" manual, but cannot seem
to find the issue addressed for multiple bolt rows.
Is this something that is typically ignored? Or, perhaps avoided
by using a single bolt row at all cost?
