Seated Tee
Tee
Length: The distance from the edge of the W tee that welds to the column to the opposite edge of the W tee (see example ).
Material ( not depicted ): The W tee section size to be used for the joist top chord seat. For example, WT9x65. The section size you enter here must exist in the local shape file and must be a tee, or validation will not accept your entry. To enter a W tee, 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 W tees in the local shape file . If this field is unlocked (
Bolts in seat
Diameter ( not depicted ): The bolt diameter. 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 " entered above, set the diameter of holes the bolts go into.
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 below, set the diameter of holes for bolts to the top chord of the supported joist.
Rows : The number of rows of holes ( 0 or 1 or 2 or 3 ) for bolting the tee seat to the joist. ' 0 ' rows results in no holes. If ' 2 ' or ' 3 ' rows are entered, the " Bolt spacing " that is set for the bolt diameter, in Connection Detailing/Fabricator Options , is applied as the row spacing. ' 1 ' row is shown in the example .
Horizontal to holes ( minus to holes ): The distance from the end of the joist to the center of the first row of holes in the tee (see example ). To calculate where the end of the joist is positioned, you need to subtract the " Setback " (" Field clearance " or " Input minus dimension " or " Automatic minus dimension ") for that end of the joist.
Gage: The distance (center to center) between the two columns of holes in the tee seat (see example ).
Welds
Seat ( not depicted ): The weld size for shop welding the W tee seat to the supporting column's web or flange (see example ).Setting the " Seat " weld to ' 0 ' (zero) removes the weld.
