Stub connection (119)

Stub connection (119) creates a connection between an H(I) type of column and a beam. The beam can be of any type. The connection can create eight stiffener plates and four haunch plates. The end plates are bolted to each other, and the other plates are welded.

Objects created

  • End plates

  • Haunch plates

  • Stiffeners

  • Bolts

  • Welds

Use for

Situation Description

Stub connection with bolted end plates and haunch plates.

The secondary part can be skewed or sloped. Top and bottom haunch plates can be created.

1 Secondary part web not directed to the center of the column (top view).

2 Secondary part web not perpendicular to the column horizontally (top view).

3 Secondary part web not perpendicular to the column vertically (side view).

Selection order

  1. Select the main part (column).

  2. Select the secondary part (beam).

Parameters tab

Use the Parameters tab to control the stiffener creation, position and chamfers.

Stiffener creation

Option Description

Default

Full

Creates a full stiffener of the same height as the web of the main part.

AutoDefaults can change this option.

Full

Creates a full stiffener of the same height as the web of the main part.

Full, both sides of the main part

Creates a full stiffener of the same height as the web of the main part.

Stiffener gap

Description

1

Distance between the stiffener and the column web

2

Distance between the stiffener and the column flange

Stiffener positions

Description

1

Size of the gap between the top stiffener and the beam flange edge.

2

Size of the gap between the bottom stiffener and the beam flange edge.

Chamfer dimensions

Description

1

Bolts tab

Use the Bolts tab to define the bolt properties.

Bolt group dimensions

Description

1

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.

2

Dimension for vertical bolt group position.

3

Dimension for horizontal bolt group position.

4

Bolt edge distance.

Edge distance is the distance from the center of a bolt to the edge of the part.

5

Bolt edge distance.

Edge distance is the distance from the center of a bolt to the edge of the part.

6

Number of bolts.

7

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.

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

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.
