Moment End Plate " & " Bolts " & " Moment Stiffeners " connection design locks
| A moment end plate is symmetrical around the center line of the supported beam's cross section and designed per " Moment End Plate " & " Bolts " & " Moment Stiffeners " locks. " Columns " of holes & " Horizontal hole spacing " are duplicated on each side of the plate. Moment end plates can be applied to beam-to-column and beam splice framing situations.

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 (

Moment End Plate
End Plate
Top of plate ( top ): The positive (+) or negative (-) vertical distance from the top edge of the end plate to the top flange of the supported beam. This distance is negative in the example shown. ' 0 ' places the top edge of the end plate even with the top flange of the beam. A positive (+) distance places the top edge of the end plate that distance below the top flange of the beam. A negative (-) distance places the end plate that distance above the top flange of the beam.
End connection failure message: Locked top of plate should be a negative value
Plate depth ( depth ): The distance between the top and the bottom edges of the end plate (see example ). If " Plate depth " is unlocked (
End connection failure message: Connection geometry fails due to locked plate/angle length
Plate width NS ( width NS ): The horizontal distance between the beam web center line and the vertical edge of the end plate that is on the near side of the beam (see example ). If " Plate width NS " is unlocked (
Plate width FS ( FS width ): The horizontal distance between the beam web center line and the vertical edge of the end plate that is on the far side of the beam (see example ).
Plate thickness ( thickness ): The " Material thickness " of the end plate (see example ).
End connection failure message: Moment end plate thickness less than required for bending stress
Bolts
Bolt diameter ( not depicted ): You can either type in any diameter (inches or mm), or you can select a bolt diameter from the combo box (
). The diameters that are listed in the combo box come from Home > Project Settings > Job > Bolt Settings > the " Available bolts " list. The bolt diameter entered here together with the " Hole type " set the diameter of holes the bolts go into.
End connection failure message: Bolt tension capacity exceeded for moment end plate connection
Hole type ( not depicted ): Standard round or Short slot or Oversized or Long slot or User slot #1 or User slot #2 . The hole type selected here, together with the " Bolt diameter " entered above, set the hole diameters.
Vertical edge distance ( ved ): The distance from the top edge of the moment end plate to the center of the nearest row of holes (see example ).
Bottom edge distance ( bed ): The distance from the bottom edge of the moment end plate to the center of the nearest row of holes (see example ).
Columns: The total number of columns of holes on either the near side or the far side of the end plate, but not on both sides. In other words, enter half of the total number of columns of holes on the entire end plate (column spacing runs horizontally). In the example shown, this number is ' 2 '. Changing the number of " Columns " also causes connection design to adjust the " Plate width NS " and " Plate width FS ."
Gage NS ( NS ): The distance from the beam web center line to the nearest column of holes on the near side half of the moment end plate (see example ). Changing the " Gage NS " also changes the " Plate width NS ."
Gage FS ( FS ): The distance from the beam web center line to the nearest column of holes on the far side half of the moment end plate (see example ). Changing the " Gage FS " also changes the " Plate width FS ."
Horizontal hole spacing ( spc ): The distance (center to center) between any two columns of holes on either side (near side or far side) of the moment end plate (see example ). The near side of the moment end plate is the half that is on the near side of the supported beam. If " Plate width NS " and " Plate width FS " are unlocked (
Horizontal edge distance NS ( hed NS ): The distance from the near side vertical edge of the end plate to the center of the nearest column of holes.
Horizontal edge distance FS ( FS hed ): The distance from the far side vertical edge of the end plate to the center of the nearest column of holes.
Weld size ( weld ): The weld size for shop welding the moment end plate to the web of the supported beam (see example ). To remove the weld, set the " Weld size " to ' 0 ' (zero).
End connection failure message: Weld strength to supporting member exceeded

Bolts
( for a moment end plate )
Interior bolts
Rows ( rows interior ): The total number of rows of interior bolts. If there is ' 1 ' row, as is the case in the example above, then that row will be positioned the " Vertical to 1st hole " distance below the top flange of the beam.
Vertical to 1st hole ( to 1st interior ): The vertical distance from the work line of the beam (its top flange) to the nearest row of interior bolts. This value will be ' 0 ' if there are no interior bolts.
Vertical hole spacing ( interior spacing ): The vertical distance (center to center) between the " Rows " of interior bolts and other adjacent rows of bolts. In the example above, where there is only a single row of interior bolts, this is the distance from that row to the nearest of the " Rows " below the top flange and to the nearest of the " Rows " above the bottom flange. (see example ).
Moment bolts
Vertical hole spacing ( spc ): The distance (center to center) between the " Rows " above top flange, the " Rows " below top flange, the " Rows " above bottom flange, and the " Rows " below bottom flange.
Distance to bottom bolt group ( not depicted ):
Bolts above top flange
Rows ( rows above top flange ): The number of rows of holes above the top flange of the supported beam (see example ). The first of these rows is positioned per " Vertical to 1st hole " (below). Additional rows above the first row are assigned the " Row spacing " for moment bolts.
End connection failure message: Moment bolt row in 4/8-bolt pattern end plate should not be modified
Vertical to 1st hole ( to 1st above top flange ): The vertical distance from the top flange of the beam (the beam work line ) to the center of the nearest of the " Rows " above the top flange (see example ). If " Top of plate " and " Plate depth " are unlocked (
Bolts below top flange
Rows ( rows below top flange ): The number of rows of holes below the top flange of the supported beam (see example ). The first of these rows is positioned per " Vertical to 1st hole " (below). Additional rows below the first row are assigned the " Row spacing " for moment bolts.

Moment Stiffeners
Weld to beam ( weld to bm ): This applies to both the top and bottom stiffener. It is the weld size for shop welding the moment end plate stiffener to the top flange of the supported beam. The example shows this weld for the bottom stiffener only. To remove the weld, set the " Weld size " to ' 0 ' (zero).
Weld to end plate ( weld to ep ): This applies to both the top and bottom stiffener. It is the weld size for shop welding the moment end plate stiffener to the end plate. The example shows this weld for the top stiffener only. To remove the weld, set the " Weld size " to ' 0 ' (zero).
Top stiffener
Plate depth ( depth ): The distance from the stiffener's edge that welds to the beam to its corner that is at highest elevation (see example ). In other words, this is length the edge of the stiffener plate that welds to the end plate. This dimension is vertical if the column is perfectly vertical.
Plate width ( width ): The distance between the two corners of the stiffener plate on the edge that welds to the top flange of the beam (see example ). In other words, this is length of the edge of the stiffener plate that welds to the beam. This dimension is horizontal if the column is perfectly vertical.

Bottom stiffener
Plate depth ( depth ): Same as the " Plate depth " for the top stiffener, except that this applies to the bottom stiffener.
Plate width ( width ): Same as the " Plate width " for the top stiffener, except that this applies to the bottom stiffener.
