Setup: Plate extension for welded moment to column web , Top flange moment stiffener location in column web , Corner operation for moment flange plates and column flange stiffeners .
User Defined Connections: Settings that are locked (
) in a user defined connection file will automatically be locked on a member edit window for which that file is the " Input connection type ." You can, if you so choose, manually lock additional settings on the member edit window, and your changes will be retained, through multiple processes, so long as you do not change to a different connection then switch back to the original user defined connection.
Beam Edit: To change a setting, first set it to locked (

Top Moment Plate / Bottom Moment Plate
Welded moment stiffener plates
Plate length ( length ): The distance (parallel with the work line of the beam) between the edge of the welded moment stiffener plate that welds to the column web and the edge opposite to that edge (see example ).
Plate width ( width ): The distance (perpendicular to the work line of the beam) between the two edges of the welded moment stiffener plate that are parallel with the work line of the beam (see example ).
Plate thickness ( not depicted ): The " Material thickness " of the welded moment plate. Also see : " Increase flange stiffener thickness by " (a setup option).
Corner clip/cope ( clip/cope ): Corner clips are 45 degree cuts at the two corners of the plate edge that welds to the column web. The cuts are made so that the plate clears the web fillet (see example ). If " Corner operation for moment flange plates and column flange stiffeners " in Plate Design Settings is set to ' Cope ', then a cope is made instead of a cut. The distance entered here is the distance (parallel with the work line of the beam) from the original corner of the plate (before it was cut) to the corner of the cut. Entering ' 0 ' results in no corner clip or cope.
Taper length: The distance (parallel with the work line of the beam) from one corner of either taper cut to the other corner of that same cut (see example ). Note that there are two taper cuts. The " Taper length " applies to each of these cuts. To remove a taper, set the " Taper length " to ' 0 ' and enter a ' Taper Width ' that is equal to the ' Plate width '. Also see : " Plate extension " (a setup option).
Taper width: The length of the plate edge that is opposite to (and parallel with) the plate edge that welds to the column web (see example ). To remove a taper, enter a " Taper width " equal to the " Plate width " and set the " Taper length " to ' 0 '. Also see: " Plate extension " (a setup option).
Welds
Transverse weld ( trans weld ): The weld size for shop welding the welded moment plate to the web of the supporting column (see example ). This weld is perpendicular to the beam's work line .
Parallel weld: The weld size for shop welding the welded moment plate to the flanges of the supporting column. (see example ). This weld runs parallel with the beam's work line .
