Frame Data - Flange Braces
(Revised: 01/06/20)

The Flange Brace tab is used to Insert, Revise, or Delete the Flange Braces on Frames.
This tab allows you to modify multiple wall or roof sides at any time.
It is possible to insert stiffeners into a member prior to frame design and detailing.

The options for Flange Braces will vary depending on the detail selected.

The locations of the Flange Brace are measured from the floor line along walls and from the ridge or high side on rafters.
Refer to: Frame Data - Work Points

List:

This list box contains the Flange Braces that are on the selected Frame Column(s) or Rafter(s).

If multiple columns or rafters are selected with different Flange Brace criteria, the list will indicate the unique conditions.

Options:

Type

This drop list is used to select Flange Brace type.

The GFB is a 2 1/2" x 2 1/2" x 0.113 angle with 1/2" diameter bolts.

The HFB is a 2 3/4" x 2 3/4" x 0.140 gage angle with 1/2" diameter bolts.

The 12MDA is a 3" x 3" x 3/16" angle with 1/2" diameter bolts.

The 12MDB is a 3" x 3" x 3/16" angle with 3/4" diameter bolts.

Side(s)

This drop list is used to define which side(s) of the web the Flange Brace (s) is located on (One Side or Both Sides).

Length

This edit box is used to define the overall length of the Flange Brace.

The length can be revised by selecting the Length checkbox. This disables the Dimensions A and B.

Dimension A

This edit box is used to define distance from the center of the column or rafter to the center of hole in the secondary member.

Dim A can be revised by selecting the Dim A checkbox.

Column Depth	Dimension A
0” – 28”	1’-10 1/2”
>28” – 42”	2’-10 1/2”
>42” – 60”	3’-10 1/2”

For 2006 IBC (2005 AISC), Dim A may be increase by design to 3’-10 1/2”.

Dimension B

This edit box is used to define distance from the Outside Flange of the Secondary member to the center of hole in the secondary.

Frame Depth

This edit box is displays the depth of the frame including flanges at the Flange Brace location.

Detail Button

This button will display the Detail options, if a detail is selected from the options pictured, it will automatically update the Detail drop list.

Each detail indicates how the flange brace is located.

Detail Drop List

This drop list allows you to select the Detail without having to use the selection options from the Detail button.

Flange Brace Ends

Hardware button will display the Hardware options for the Flange Brace attachment.

Hardware options can be chosen for the Frame and/or Secondary end of flange brace.

Orientation - 0.0

This radio button orientates the bent leg of a Flange Brace toward the work point (End 1).

Orientation - 180.0

This radio button orientates the bent leg of a Flange Brace away from the work point (End 1).

Holes, Clips, Stiffeners, Flange Braces, Brackets, & Misc Clips Locations

(The method used to locate parts on a frame side is the same on all Frame Data tabs.)

Location:

Based on the radio button option selected, the location options will be enabled or disabled as required.

Radio Button Options

End 1 / End 2

These radio buttons set the measurement method along the Wall Side (building line / girt line) or the Roof Side (roof line / purlin line). End 1 on a Wall Side are measured from the Finished Floor Elevation, a positive dimension is upward. End 1 on a Roof Side is from the ridge (or high side), a positive dimension is down-slope (along the slope). End 2 is measured from the low eave.

Member

This option sets the measurement method along a Designed Frame Member. The locations along a column member are measured from the lowest point of the member (along the outside flange) inside any applicable base plate or splice plate, a positive dimension is upward. The Locations along a rafter member are from the highest point (along the outside flange) inside any applicable splice plate, a positive dimension is down-slope (along the slope). The measurement options will be enabled or disabled as required.

Note: This option is not available if the frames have not been designed.

Horizontal

This option sets the measurement method parallel to the floor. This enables the location to be a horizontal dimension from the work point.

Note: This option is only available on rafters.

Vertical

The option sets the measurement method perpendicular to the floor, measured from the Finished Floor Elevation.

Note: This option is only available on columns.

X and Y

The X and Y radio button sets the measurement method of locating stiffeners using a 2D coordinate value, from the work point. The measurement options will be enabled or disabled as required.

„ How to use:

On rafters, the X coordinate will be a negative dimension down from the work point (ridge point or high eave point) at the sheet line.

This option is intended for use on webs, though it can also be used on a flange if desired.

„ How to use:

Comparing the usage of all radio button options: "End 1" is used most frequently.

Location

Total Distance (read only)

This displays the overall length of the Wall Side or Roof Side selected. If multiple columns or rafters are selected with varying lengths, this box will not display a length.

Quantity of Spaces / Spaces At

This edit box is used to insert multiple locations into the list. It is used in conjunction with the Spaces At edit box.

You can insert into the middle of the existing list by selecting a row in the list prior to entering the location information. The locations will be added prior to the row selected without moving the active row.

This edit box defines the distance between the locations inserted into the list. Inserting new rows is used in conjunction with the Quantity of Spaces edit box. Revising a Space will automatically adjust all of the following spaces to new locations.

Location At

This edit box is used to insert or revise a specific location in the list. Locations will be added or modified in the list without moving any other row.

You can insert into the middle of the existing list without selecting a row from the list.

„ How to use:

Comparing the usage of both locating methods "Spaces At" & "Location At": "Location At" is used most frequently.
