Objects created

  • End plates

  • Shim plates

  • Ear plates

  • Stiffeners

  • Bolts

  • Welds

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 that is shown in drawings and reports.

Finish

Describes how the part surface has been treated.

Shim plate bolt edge distance

Description

1

Horizontal bolt edge distance in the shim plate.

2

Vertical bolt edge distance in the shim plate.

Shim plate shape

Option Description

Default

Holes are based on the bolt group of the connection.

AutoDefaults can change this option.

Holes are based on the bolt group of the connection.

Finger shim plate with horizontal slots.

The plate can be installed from the right or the left side of the connection.

Finger shim plate with vertical slots.

The plate can be installed from the top of the connection.

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. For two separate shim plates, also define the tolerance between the plates.

Parameters tab

Use the Parameters tab to define ear plate creation and dimensions.

Dimensions

Description Default

1

Number of ear bolts

You can define the number of the holes in the horizontal and vertical direction.

Horizontal: 1

Vertical: 2

2

Ear bolt spacing

3*hole diameter

If there are more than two bolts in the bolt group in one direction, give the distances separated by a space (for example, 40 50).

3

Ear bolt edge distance

Edge distance is calculated from the top and outside edges.

2.5*hole diameter

4

Ear bolt hole diameter

5

Bolt edge distance to the edge of the shim plate

Ear plate creation

Option Description

Default

Both ear plates are created.

AutoDefaults can change this option.

Both ear plates are created.

Ear plate 1 is created.

Ear plate 2 is created.

Gap size

Define the limit value for the gap between the end plate and the secondary beam. Use this when the beam is slightly curved or sloped to decide if the end angle is so small that the beam end can be straight.

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

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

Bolts tab

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

Bolt group dimensions

1

Dimension for horizontal bolt group position.

2

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.

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

Dimension for vertical bolt group position.

7

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.

8

Define which bolts are deleted from the bolt group.

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

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 or tapped holes.

No hole does not create 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.

Staggering of bolts

Option

Description

Default

Not staggered

AutoDefaults can change this option.

Not staggered

Staggered type 1

Staggered type 2

Staggered type 3

Staggered type 4

Holes tab

Use the Holes tab to control the galvanizing holes in the end plates.

Option Description

Bolt standard

Select the bolt standard.

Bolt type

Select the bolt type to define the location where the bolts should be attached.

Read data from

You can select to use the sinkholes.dat definition file to specify the default values for horizontal and vertical offsets, and the diameters for upper and lower holes.

The file is searched in the following order: Environment common system steel folder (..\Environments\common\system\Steel), model folder, XS_FIRM, XS_PROJECT and XS_SYSTEM folder.

You can also select to define the holes in the component dialog box.

Number of holes

The center of a hole group is the middle point of the beam and the middle point of the haunch, if the haunch exists. The hole groups are composed of 0, 1, 2, or 4 holes.

Option Description

Default

No holes

AutoDefaults can change this option.

No holes

1 hole

2 holes

4 holes

Hole positions

1

Horizontal distance between the end plate center and the upper hole.

2

Horizontal distance between the end plate center and the lower hole.

3

Vertical distance between the end plate center and the upper hole.

4

Vertical distance between the end plate center and the lower hole.

5

Diameter of the lower hole.

6

Diameter of the upper hole.
