" Web Plate " & " Upper Web Fill Plate " & " Lower Web Fill Plate "

NS and FS column web splice plates are designed per " Web Plate " locks. The plates shop bolt to the lower column and field bolt to the upper. An upper fill plate may be designed per " Upper Web Fill Plate " locks when the upper column web thickness is less than the lower.

(column end, web splice plate connection, to column end)
(" Section size " for both columns = W or S or welded plate W)
(" Input connection type " = ' Splice plate ' or ' Auto standard ' or ' User defined ') (" Column attachment " =
' All-Bolted plates ') (' Web plates ')
" Web Plate "

 " Upper Web Fill Plate "
(values of ' 0 ' if fill plate not designed)
" Lower Web Fill Plate "
(values of ' 0 ' if fill plate not designed)

A fill plate may automatically be generated in the model if the two columns being spliced have unequal web thicknesses. If the column webs are equally thick, no fill plates will initially be generated in the model, but " Upper Web Fill Plate " and " Lower Web Fill Plate " connection design locks will still be provided, with their values set to zero (' 0 ') . Entering a " Fill thickness " greater than ' 0 ' will result in a fill plate of that thickness being generated.

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.

Column Edit: To change a setting, first set it to locked ( ). Related settings that are unlocked ( ) may be updated, and the " Left/Right end limit state " calculations will be updated. Settings that are locked ( ) will not be changed by connection design , even if doing so might prevent a connection failure.

  Web Plate
( column splice connection )

Web plate

Plate length lower ( length lower ): The distance (parallel with the work lines of the columns) from the top work point (" End elevation ") of the lower column to the bottom edge of the web splice plate (see example ). If the " Plate length lower " is unlocked ( ), changing the bolt " Rows " (lower) or " Vertical spacing " (lower) also changes the " Plate length lower ." " Vertical to holes " (lower) moves the holes without affecting the plate length.

Plate width ( width ): The length of the top or bottom edge of the web splice plate (see example ). For a perfectly vertical column, " Plate width " is the horizontal distance between the two vertical edges of the web splice plate. If " Plate width " is unlocked ( ), changing the bolt " Columns " (upper) or " Horizontal gage " (upper) or " Horizontal spacing " (upper) or bolt " Columns " (lower) or " Horizontal gage " (lower) or " Horizontal spacing " (lower) may also change the " Plate width ."

Plate thickness ( not depicted ): The " Material thickness " of the web splice plate. This applies to both the near side and far side web splice plates.

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 web of upper column. It applies to the web plates on both sides of the web.

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 web plate that bolts to the upper column. It applies to the web plates on both sides of the web.

Rows ( rows upper ): The number of rows of bolts on the part of the web 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 ( ), changing the number of bolt " Rows " (upper) also changes the " Plate length upper . "

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 " (upper) moves the holes on the plate but does not change 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 web splice plate that field bolts to the web 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 ( ) and the number of bolt " Rows " (upper) is ' 2 ' or greater, changing the " Vertical spacing " (upper) also changes the " Plate length upper ."

Columns ( columns upper ): Half the total number of columns of bolts on the part of the splice plate that field bolts to the web of the upper column. Bolt column spacing runs perpendicular to the work lines of the columns being spliced. For the web splice plate connection represented in the example above, the number of " Columns " is ' 2 ', which results in a total of four bolt columns. If " Plate width " is unlocked ( ), changing the number of bolt " Columns " may also change the " Plate width ."

Horizontal spacing ( col sp ): The distance (center to center) between any two adjacent columns of holes other than the two inside columns of bolts on the half of the web plate that field bolts to the web of the upper column (see example ). Bolt column spacing runs perpendicular to the work lines of the columns being spliced. If " Plate width " is unlocked ( ) and the number of bolt " Columns " (upper) is ' 2 ' or greater, changing the " Horizontal spacing " (upper) may also change the " Plate width ."

Horizontal gage ( gage upper ): The distance (center to center) between the two inside columns of bolts on the part of the web splice plate that is above the " End elevation " of the bottom end of the upper column. Bolt column spacing runs perpendicular to the work lines of the columns being spliced -- see example . If " Plate width " is unlocked ( ), changing the " Horizontal gage " (upper) may also change the " Plate width ."

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 web of lower column. It applies to the web plates on both sides of the web.

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 web plate that bolts to the lower column. It applies to the web plates on both sides of the web.

Rows ( rows lower ): The number of rows of bolts on the part of the web 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 web splice plate connection in the example , the number of " Rows " (lower) is ' 2 '. If the " Plate length lower " is unlocked ( ), changing the number of bolt " Rows " (lower) also changes the " Plate length lower ."

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 ). Changing the " Vertical to holes " (lower) moves the holes on the lower half of the plate but does not change the dimensions of the plate.

Vertical spacing ( row spc lower ): The distance (center to center) between any two adjacent rows of bolts on the part of web splice plate that shop bolts to the web of the lower column. Bolt row spacing runs parallel with the work lines of the columns being spliced -- see example . If the " Plate length lower " is unlocked ( ) and the number of bolt " Rows " (lower) is ' 2 ' or greater, changing the bolt row " Vertical spacing " (lower) also changes the " Plate length lower ."

Columns ( columns lower ): Half the total number of columns of bolts on the part of the web splice plate that shop bolts to the web of the lower column. Bolt column spacing runs perpendicular to the work lines of the columns being spliced. For the web splice plate connection in the example , the number of bolt " Columns " is ' 2 ', which results in a total of four bolt columns. If " Plate width " is unlocked ( ), changing the number of bolt " Columns " may also change the " Plate width ."

Horizontal spacing ( col spc ): The distance (center to center) between any two adjacent columns of bolts other than the two inside columns of bolts on the part of the splice plate that bolts to the web of the lower column (see example ). Bolt column spacing runs perpendicular to the work lines of the columns.
