" Gusset 2 Point Square " & " Brace Connection to Gusset " & " Weld Conn2 " connection design locks

An angle, W tee or channel vertical brace field bolts directly to a shared gusset plate per choices made to " Brace Connection To Gusset ." The corner of the gusset is square under the brace because " Clip end operation " is set to ' No ' or, possibly, to ' Automatic '. Gusset-to-column shop attachment is per locks in " Weld Conn2 " or, when applicable, " NS/FS Clip Conn2 ." The shared gusset may be for 2-point bracing (" Gusset 2 Point Square ") or 3-point bracing (not shown).

2-point and 3-point bracing . The connection design locks for 2-point bracing (2 braces to a shared gusset) and 3-point bracing are essentially the same. However, you cannot connect a 3-point gusset plate to the supporting beam with a clip angle. A 3-point gusset plate must be welded to the supporting beam. In pre-v2017 releases, the middle brace for 3-point bracing needed to be perpendicular to the supporting beam -- that is no longer true.

User Defined Connections: Settings that are locked ( ) in the user defined connection file will automatically be locked on the member edit window. 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.

Vertical Brace 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.

    Gusset 2 Point Square
(L or WT or C vertical braces, 2- or 3-point, to a beam)
(" Clip end operation " = ' No ' or possibly ' Automatic ')

Shared gusset plate dimensions and location

Plate thickness ( not depicted ): The " Material thickness " of the gusset plate.

Width ( plate width ): The distance (perpendicular to the column's work line ) between the two longest edges of the gusset plate (see example ). The gusset plate " Width " can also be defined as the length of either one of the two edges of the shared gusset plate that are perpendicular to the work line of the column.

Length ( plate length ): The length of the framing edge of the gusset plate (which welds to the supporting column in the example shown). If the column is perfectly vertical, this is the vertical distance (parallel with the supporting column's work line ) between the two horizontal edges of the gusset plate.

Refy: The positive (+) or negative (-) distance (perpendicular to the supporting column's work line ) from the work point of the vertical brace to the framing edge of the gusset plate (which welds to the column's bottom flange in the example shown). Changing the " Refy " moves the gusset plate perpendicular to the work line of the column (horizontally if the column is vertical), but does not move the holes on the plate.

Left Brace [ member number ] (the left brace is the bottom brace if the column is vertical)

Refx ( refx left ): The positive (+) or negative (-) distance (parallel with the supporting column's work line ) from the work point of the left vertical brace to the corner of the framing edge of the gusset plate that is closest to the left end of the column (see example ). For a shared gusset plate to a perfectly vertical column, this distance is vertical. Changing the " Refx " moves the gusset plate parallel with the work line of the column, but does not move the holes on the plate. Hole positioning is governed by the " Brace Connection To Gusset " connection design locks.

Right Brace [ member number ] (the right brace is the upper brace if the column is vertical)

Refx ( refx right ): The positive (+) or negative (-) distance (parallel with the supporting column's work line ) from the work point of the right vertical brace to the corner of the gusset plate's framing edge that is closest to the right end of the column. This works similar to the way that " Refx " works for the left vertical brace.

Hole pattern for field bolting the braces to the gusset plate

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 " entered below, 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 above, set the diameter of holes for field bolting the supported brace to the half of the gusset plate you are editing.

Rows: The number of holes in the column of holes with the greatest number of holes. Bolt row spacing on a vertical brace gusset plate runs parallel with the work line of the vertical brace (see example ). For an angle vertical brace, this is the number of rows of holes in the column of holes along the work line of the brace. For vertical braces of other types of material, this is the number of rows in any one column of holes. Entering ' 0 ' removes the holes. For the angle brace shown in the example above, the number of " Rows " is ' 4 '.

Distance to 1st hole along brace ( to 1st hole ): The distance (parallel with the work line of the brace) from the work point to the center of the nearest row of holes. For the example above (an angle brace with staggered bolts), the nearest row of holes is the nearest hole on the work line.

Hole spacing along brace ( rs ): Row spacing. This is the distance (center to center) between of any two adjacent holes in the same column of holes (see example ).

End connection failure message: Invalid bolt spacing

Edge distance along brace ( edge dist ): The distance from the forward edge of the brace to the nearest hole for field bolting that brace to the gusset plate (see example ). The forward edge of the brace is the edge that is closest to the work point of the brace.

Columns: The number of columns of holes in the half of the gusset that is being edited. These holes will be used for field bolting the vertical brace to its half of the shared gusset. Columns spacing runs perpendicular to the work line of the vertical brace. In the example above, the number of " Columns " is ' 2 '.

Hole spacing perpendicular to brace ( cs ): Column spacing. This is the distance (center to center) between any two adjacent columns of holes in the half of the gusset being edited (see example ). Bolt column spacing runs perpendicular to the work line of the vertical brace.

  Weld Conn2
( L or WT or C vertical braces, 2- or 3-point )

Shop weld, shared gusset to the supporting column

Weld size ( weld ): The weld size for shop welding the gusset plate to the supporting column (see example ). Gussets for 2-point bracing can optionally be shop-bolted to the beam with a clip angle (" NS/FS Clip Conn2 "). 3-point gusset plates must be welded to the column. Regardless of whether it is shop welded or shop bolted, the gusset will be detailed with the beam and field bolted to the vertical brace.

To get a weld (" Weld Conn2 "), select ' Welded ' for " Gusset to supporting member " under " Connection specifications " on the Vertical Brace Edit window.

To instead get a clip angle (" NS/FS Clip Conn2 "), select ' Clip Angle ' for " Gusset to supporting member ."
