Use for


Situation	Description
	Brace profile: Tube Gusset plate is welded to the beam. Braces are bolted to the gusset plate using tees.
	Brace profile: RHS Gusset plate is welded to the column. Braces are bolted to the gusset plate using tees.

Limitations

The braces must be in the same plane.

Before you start

Create a beam, and up to three braces all in the same plane.

Selection order

Select the main part (beam or column).
Select the secondary part (first brace).
Select the second secondary part (second brace).
Select the subsequent secondary part (third brace).
Click the middle mouse button to create the component.

Part identification key


	Description
1	Gusset plate
2	Tee

Picture tab

Use the Picture tab to define the tee dimension from the gusset plate edge.


	Description
1	Define the tee edge dimension.

Parts tab

Use the Parts tab to define the properties of the gusset plate, and the tees at the ends of the braces. You can define the tees separately for each brace.

Parts


Option	Description
Gusset	Thickness, width and height of the gusset plate.
Tee flange	To have Tekla Structures use two plates to create the tee, leave the Tee profile empty. You must enter the thickness, width, and height dimensions for the tee flange and web instead. Define the thickness, width and height of the tee flange.
Tee web	To have Tekla Structures use two plates to create the tee, leave the Tee profile empty. You must enter the thickness, width, and height dimensions for the tee flange and web instead. Define the thickness, width and height of the tee web.
Tee profile	Select the tee profile from the profile catalog. You can use a T profile or an I profile. If you use an I profile, the component creates the tee by cutting the I profile. You must specify where to cut the I profile, using the tee depth option on the Parameters tab.


Option	Description	Default
Pos_No	Prefix and start number for the part position number. Some components have a second row of fields where you can enter the assembly position number.	The default part start number is defined in the Components settings in File menu > Settings > Options.
Material	Material grade.	The default material is defined in the Part material box in the Components settings in File menu > Settings > Options.
Name	Name that is shown in drawings and reports.
Class	Part class number.

Parameters tab

Use the Parameters tab to define the tee dimensions, clearances, gusset plate position and chamfers.


Option	Description
Min. cut angle (0-90 deg)	Define the minimum cut angle.
Define welds for each Tee	Select whether to use welds for each tee.
Define bolts for each Tee	Select whether to use bolts for each tee.

Gusset position

Select the gusset position on the brace.

Tee position

Select the tee position on the gusset.

Gusset chamfer


Option	Description
	Default No chamfer AutoDefaults can change this option.
	No chamfer
	Chamfers are created.

Tee dimensions

Define the tee dimensions for each brace.


	Description
1	Tee length
2	Tee depth

Bolt group alignment

Select whether bolt groups are aligned.

Gusset position on the main part


Option	Description
	Default Gusset is positioned according to the defined distances. AutoDefaults can change this option.
	Gusset is positioned according to the defined distances.
	Gusset is centered to the center of the bolt group.
	Gusset is centered to the center of the connection origin.

Bolts 1 / Bolts 2 / Bolts 3 tabs

Use the Bolts 1, Bolts 2 and Bolts 3 tabs to control the bolts that connect the first, the second, and the third brace to the gusset plate.

Bolt group dimensions


	Description
1	Plate edge distance to the main part web.
2	Bolt edge distance. Edge distance is the distance from the center of a bolt to the edge of the part.
3	Number of bolts.
4	Bolt spacing. Use a space to separate bolt spacing values. Enter a value for each space between bolts. For example, if there are 3 bolts, enter 2 values.

Bolt basic properties


Option	Description	Default
Bolt size	Bolt diameter.	Available sizes are defined in the bolt assembly catalog.
Bolt standard	Bolt standard to be used inside the component.	Available standards are defined in the bolt assembly catalog.
Tolerance	Gap between the bolt and the hole.
Thread in mat	Defines whether the thread may be within the bolted parts when bolts are used with a shaft. This has no effect when full-threaded bolts are used.	`Yes`
Site/Workshop	Location where the bolts should be attached.	`Site`

Slotted holes

You can define slotted, oversized, or tapped holes.


Option	Description	Default
1	Vertical dimension of slotted hole.	`0`, which results in a round hole.
2	Horizontal dimension of slotted hole, or allowance for oversized holes.	`0`, which results in a round hole.
Hole type	Slotted creates slotted holes. Oversized creates oversized holes. No hole does not create holes. Tapped creates tapped holes.
Rotate Slots	When the hole type is Slotted, this option rotates the slotted holes.
Slots in	Part(s) in which slotted holes are created. The options depend on the component in question.
