Top Moment Angle " & " Bottom Moment Angle " connection design locks
| Moment restraining angles can bolt to the top and bottom flanges of a wide flange or welded plate wide flange beam and are designed per " Top Moment Angle " and " Bottom Moment Angle " locks. Welded restraining angles are not supported. The web connection (not shown) can be clip angles or a single-plate shear connection.

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 Angle / Bottom Moment Angle
Moment angle
Material ( not depicted ): The section size of the angle to be used. For example, L4x3x5/16. The section size you enter here must exist in the local shape file and must be an angle, or validation will not accept your entry. To enter an angle section size, you can type in the section size that you want, or you can press the "file cabinet" browse button (
) and double-click any section that is on the list of available angles in the local shape file . If this field is unlocked (

Long leg to ( not depicted ): Supported or Supporting . If you want the long leg of the angle to attach to the supporting column, select ' Supporting '. If you want the long leg of the angle to attach to the supported beam, select ' Supported '.
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 supported " and " Hole type supporting ") determine the diameter of holes the bolts go into.
Angle length ( length ): The distance between the near-side and far-side edges of the angle (see example ). The near side edge of the angle is on the near side of the supported beam. The far side edge is on the far side of the beam. This distance is measured perpendicular to the work line of the beam and is a horizontal distance if the column is perfectly vertical.
Connection to supported ( shop bolts to the restraining angle leg to the supported beam )
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 diameter of holes on the leg of the angle that shop bolts to the supported beam.
Rows ( rows supported ): The number of rows of holes in the leg of the restraining angle that shop bolts to the top/bottom flange of the supported beam (see example ). An entry of ' 0 ' (zero) allows you to create a welded flange angle, which is a connection type that connection design does not support. In the example above, the number of " Rows " in the leg to supported is ' 2 ' (annotated for the top flange angle only).
Horizontal to 1st hole ( 1st ): The distance from the heel of the angle to the center of the first row of holes on the angle leg that shop bolts to the top/bottom flange of the supported beam. In the example above, this distance is annotated only for the top flange moment restraining angle. This distance is measured paralell with the work line of the beam and is horizontal if the column is perfectly vertical. Changing the " Horizontal to 1st hole " moves all of the holes on the angle leg to supported and does not move the angle.
Row spacing ( rsp ): The distance (center to center) between rows of holes in the leg of the angle that shop bolts to the top/bottom flange of the supported beam. In the example above, this distance is annotated only for the top flange moment restraining angle. This distance is measured paralell with the work line of the beam and is horizontal if the column is perfectly vertical.
Columns ( columns supported ): Half of the total number of columns of holes in the leg of the restraining angle that shop bolts to the top/bottom flange of the supported beam. In other words this is the total number of columns of holes for the near side or far side top or bottom flange of the beam. In the example above, the number of these rows is ' 2 ' and the total number of bolt rows to the supported beam is ' 4 '.

Gage ( ga/ed ): The distance (center to center) between the two columns of holes that are closest to the work line of the supported beam (that is, between the two inside columns of holes on the leg of angle to the top or bottom flange of the supported beam). In the example above, this dimension is annotated only for the top flange restraining angle. The distance is measured perpendicular to the work line of the beam and is a horizontal distance if the column is perfectly vertical. The unlocked (

Column spacing ( csp ): The horizontal distance (center to center) between any two adjacent columns of holes that are on the same side (near side or far side) of the workline of the supported beam. In the example above, this dimension is annotated only for the top flange restraining angle. The distance is measured perpendicular to the work line of the beam and is a horizontal distance if the column is perfectly vertical.
Connection to supporting ( field bolts in the restraining angle leg to the supporting column )
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 diameter of holes on the leg of the angle that field bolts to the supporting column.
Rows ( rows supporting ): The number of rows of holes in the leg of the angle that field bolts to the supporting column (see example ). An entry of ' 0 ' (zero) allows you to create a welded flange angle, which is a connection type that connection design does not support. In the example above, the number of " Rows " in the leg to the supporting column is ' 2 ' (annotated for the top flange restraining angle only).
Vertical to hole ( vert to 1st ): The distance from the heel of the angle to the center of the first hole on the angle leg that field bolts to the supporting column (see example ). This distance is positive (+) regardless of whether it is for the top flange or bottom flange angle. It is a vertical distance if the column is perfectly vertical.
Row spacing ( rowspc ): The distance (center to center) between rows of holes in the leg of the angle that field bolts to the column. In the example above, this dimension is annotated only for the top flange moment restraining angle. " Row spacing " in the leg to supporting is a vertical distance if the column is perfectly vertical.
Columns ( columns supporting ): Half of the total number of columns of holes in the leg of the restraining angle that field bolts to the supporting column. In the example above, the number of these rows is ' 2 ' and the total number of bolt rows to the supporting column is ' 4 '. This dimension is annotated for the top flange restraining angle only.
