Can anyone suggest a good reference for design of a steel gusset plate for a
AISC Seismic Provisions for Structural Steel Buildings Section 14.3d states
that "The design of gusset plates shall include consideration of buckling."
AISC Volume II Connections, Example 19 (ASD) on page 7-138 calculates a
buckling capacity of the gusset plate using "the length of the Whitmore
section" - but no reference or explanation is given for how to determine the
Whitmore section. LRFD Volume II Connections on page 11-27 states
"Additionally, the gusset must be checked on the Whitmore Section for
yielding and for column buckling under compressive brace loads." - but no
reference is given. I've looked thru a number of steel design references but
cannot find anything on the "Whitmore section" nor a description of how to
check buckling due to compressive brace loads.
