3	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`

Cut length

Defines the depth at which Tekla Structures searches for the sections of the bolted parts. You can determine whether the bolt will go through one flange or two.

Comment

You can define a comment.

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.

Bolt assembly

The selected check boxes define which component objects (bolt, washers, and nuts) are used in the bolt assembly.

If you want to create a hole only, clear all the check boxes.

To modify the bolt assembly in an existing component, select the Effect in modify check box and click Modify.

Bolt length increase

Define how much the bolt length is increased. Use this option when, for example, painting requires the bolt length to be increased.

Parameters tab

Use the Parameters tab to define a component.

Using additional components

You can use additional system or custom components to modify the column end or the base plate. For example, you can create special backing plates, weld preparations, and weld access holes for the column end.

If you use additional system or custom components, you need to manage the column end or the base plate properties in the additional component in question. When using several components, there may be multiple welds and cuts.


Option	Description
Component	Select a system or a custom component from the Applications & components catalog.
Attributes	Select an attribute file for the component.
Input	Define to which parts the selected component is applied. Default is the same as Base + Column. Column sets the column as the main part. Use this option for details. Column + Base sets the column as the main part and the base plate as the secondary part. Base + Column sets the base plate as the main part and the column as the secondary part. Base sets the base plate as the main part.

Anchor rods tab

Use the Anchor rods tab to define the properties of the rod, nut, washer, cast plate, and grout.

Grout	Grout thickness. Grouting helps you to model columns to the top of concrete parts and place the base plate correctly. It also makes it easier to dimension the detail in GA drawings. The cast unit type of the grout is Cast in place. By default, no grouting is created. Select whether the grouting is created with or without slopes above or below the detail creation point. This also affects the shim plates.
