Plate thickness ( not depicted ): The " Material thickness " of the flange splice plate. This applies to the splices for both flanges.
Field bolts on the upper column
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 bolt diameters " list. The bolt diameter entered here (together with the " Hole type ") sets the diameter of holes through the part of the plate that bolts to the flange of upper column. It applies to splices for both flanges.
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 through the part of the plate that bolts to the flange of upper column.
Rows ( rows upper ): The number of rows of bolts on the part of the flange splice plate that is above the bottom " End elevation " of the upper column. Bolt row spacing runs parallel with the work lines of the columns being spliced -- see example . If " Plate length upper " is unlocked (
Vertical to holes ( vert to upper ): The distance (parallel with the work lines of the columns) from the bottom work point (" End elevation ") of the upper column to the center of the nearest row of bolts that is above that " End elevation " (see example ). Changing the " Vertical to holes " moves the holes on the upper half of the flange plate without affecting the plate dimensions.
Vertical spacing ( row spc upper ): The distance (center to center) between any two adjacent rows of bolts on the part of the splice plate that field bolts to the flange of the upper column. Bolt row spacing runs parallel with the work lines of the columns being spliced -- see example . If " Plate length upper " is unlocked (
Columns ( columns upper ): Half the total number of columns of bolts on the part of the flange splice plate that is above the bottom " End elevation " of the upper column. Bolt column spacing runs perpendicular to the work lines of the columns being spliced -- see example . For the splice plate connection represented in the example above, the number of " Columns " is ' 2 ', which results in a total of four bolt columns on the upper section of the flange plate. If " Plate width " is unlocked (

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 through the part of the plate that bolts to the flange of lower column.
Rows ( rows lower ): The number of rows of bolts on the part of the flange splice plate that is below the top " End elevation " of the lower column. Bolt row spacing runs parallel with the work lines of the columns being spliced. For the splice plate connection represented in the example above, the number of bolt " Rows " (lower) is ' 2 '. Entering ' 0 ' for bolt " Rows " (lower) is allowed for a welded lower/bolted upper splice connection. Users will still need to add the weld since this isn't a supported connection. If " Plate length lower " is unlocked (
Vertical to holes ( vert to lower ): The distance (parallel with the work lines of the columns) from the top work point (" End elevation) " of the lower column to the center of the nearest row of bolts that is below that " End elevation " (see example ). If the splice plate connection is designed with a butt plate, the top work point of the lower column is the exact center of the top surface of the butt plate. Changing the " Vertical to holes " (lower) moves the holes on the lower half of the flange plate without affecting the plate dimensions.
Vertical spacing ( row spc lower ): The distance (center to center) between any two adjacent rows of bolts on the half of the splice plate that shop bolts to the flange of the lower column. Bolt row spacing runs parallel with the work lines of the columns being spliced -- see example . If " Plate length lower " is unlocked (
Columns ( columns lower ): Half the total number of columns of bolts on the part of the flange splice plate that shop bolts to the flange of the lower column. Bolt column spacing runs perpendicular to the work lines of the columns being spliced -- see example . For the splice plate connection represented in the example above, the number of bolt " Columns " (lower) is ' 2 ', which results in a total of four bolt columns on the lower section of the flange plate. If " Plate width " is unlocked (
Horizontal spacing ( col spc ): The distance (center to center) between any two adjacent columns of bolts other than the two inside bolt columns (see example ). Bolt column spacing runs perpendicular to the work lines of the columns being spliced, parallel with the depths of those members. If " Plate width " is unlocked (
