a moment must be developed at the appropriate gusset interface. If ∆V b is introduced, an internal
moment will develop in the single-plate connector and all appropriate checks must be made.
Note that although the moment due to the brace force has been eliminated, a moment due to the beam
reaction must still be considered. Since the beam reaction does not have a line of action that passes
through the workpoint, it is impossible to eliminate all moments from the system, as is accom-
plished through the use of the uniform force method for the brace force. However, it is possible to move
the moment from the beam-to-column connection to the beam-to-gusset connection. Since the beam-to-
gusset connection is usually a welded and not a bolted connection, and is not limited by the depth of the
