	Two separate finger shim plates with horizontal slots.
	Two separate finger shim plates with vertical slots.

Tolerance

Define the tolerance for the slots in finger shim plates. The width of the slot is the bolt diameter + the tolerance.

Parameters tab

Use the Parameters tab to control the component and the grout hole.

Grout hole

Define whether a grout hole is created in the base plate. The hole is also created in the leveling plate and shim plates, if they exist in the detail.

Gap size

Define the limit value for the gap between the base plate and the column. Use this when the column is slightly inclined.

If the actual gap is smaller than this value, the end of the column is left straight.

If the actual gap is larger than this value, the end of the column is fitted to the base plate.

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.

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.

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.

Bolt comment

You can define a bolt 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
