Windbracing (1)

Windbracing (1) connects a single hollow brace to a beam or a column using a connection plate, threaded rod, and nuts. Round plates are welded to the connection plate and the connection plate is bolted to the beam or column.

Note:

Tekla Structures automatically attaches the rod to the brace so that the rod and the brace are treated as a single part when you use commands like DeleteMove, or Copy.

Use for


Situation	Description
	The column or beam profile is H, and the brace profile is RHS.

Selection order

Select the main part (beam or column).
Select the secondary part (brace).

The connection is created automatically when the secondary part is selected.

Parts


Option	Description
Connection plate	Thickness, width, and height of the connection plate
Round plates	Thickness, width, and height of the round plates
Filler plate	Select the profile from the profile catalog.
Washer	Select the profile from the profile catalog.
Nut	Select the profile from the profile catalog.
Extra nut	Select the profile from the profile catalog.

Brace conn tab

Use the Brace conn tab to define the properties of the hole in the beam or column, slot in the connection plate, position of round plates, and rod dimensions.

Hole type


Option	Description
Create hole in primary	Partcut cuts a hole for the rod. Bolt creates a bolt hole. Partcut+bolthole cuts a hole for the rod and creates a bolt hole.

Horizontal position of round plate

Define the horizontal offset of the round plate.

Rod dimensions


	Description
1	Rod thickness
2	Rod length, below the intersection point of the main part and secondary part
3	Rod length, above the intersection point of the main part and secondary part

Slot dimensions


	Description
1	Horizontal dimension
2	Vertical dimension

Bolts tab

Use the Bolts tab to define the bolt group dimensions and bolt properties.

Bolt group dimensions


	Description
1	Select how to measure the dimensions for horizontal bolt group position. Left: From the left edge of the secondary part to the leftmost bolt. Middle: From the center line of the secondary part to the center line of the bolts. Right: From the right edge of the secondary part to the rightmost bolt.
2	Dimension for horizontal bolt group position.
3	Bolt edge distance. Edge distance is the distance from the center of a bolt to the edge of the part.
4	Number of bolts.
5	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.
6	Select how to measure the dimensions for vertical bolt group position. Top: From the upper edge of the secondary part to the uppermost bolt. Middle: From the center line of the bolts to the center line of the secondary part. Below: From the lower edge of the secondary part to the lowest bolt.
7	Dimension for vertical bolt group position.

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.
