Front Plate Connection to Web/Flange (3-D SE)

"Civil Engineering functions" docking window > Steel Engineering > Connections > Front side to web/flange side > Front plate > Front Plate Connection to Web/Flange (2320)

Use this function to connect 2 beams via a bolted front plate connection. The connection can be made to the web or to the flange - with or without filler plates. Depending on the fitting situation, the connected beam will be automatically notched appropriately. Furthermore, weld seams can also be directly inserted and annotated.

The connection can be a user-defined connection or configured via predefined DAST tables supplied with HiCAD.

Supported beam and profile types are I-beams, U-beams, T-beams, Z-profiles, pipes and hollow profiles.

(1) Beam to be connected, (2) Target beam to which connection is to be made, (3) Created connection, (4) with filler plates

Proceed as follows:

1. Identify the beam to be connected.
2. Identify the beam to which the connection is to be made.

The dialogue window for the front plate connection will be displayed. The configuration of the front plate connection takes place via the tabs of this dialogue window.

	Selected parts Click on this symbol to show information on the previously identified beams, such as the type of the beam, the material, the dimensions, etc. Value inputs and changes are not possible here.
	Invert concerned connection values horizontally Click on this symbol to switch specified values horizontally, i.e. right and left. For instance, this can be done for Bore grid distances, grid references Plate distances, plate references Other references Example 1
	Invert concerned connection values vertically Click on this symbol to switch specified values vertically, i.e. top and bottom. For instance, this can be done for Bore grid distances, grid references Plate distances, plate references Other references Example 1

Please note:

• The front plate and the weld seams are assigned to the assembly of the beam to be connected (1st beam). Filler plates are assigned to a structure assembly called Loose parts on the same level as the assembly of the 1st beam. The bolting is inserted as a Bolting assembly. The assigning of this Bolting group and of the reinforcement plates depends on the settings on the Boltings tab.
• The weld seam tags are only defined in the dialogue, but not automatically inserted in the drawing. To insert the tags, right-click the weld seam select Insert weld seam tag and determine the start point of the tag by identifying a point or an edge.

• During input of the required data, texts will indicate in the drawing where right/left and top/bottom are. These texts are aligned in Z-direction.

Manage configurations

The configurations of the front plate connections can be saved, which enables you to access your individual configurations at any time afterwards.

More about configurations

User-defined insertion or insertion according to DAST

The insertion of the front plate connection can take place as a user-defined connection or according to DAST tables. The input/selection fields are initialised with values, depending on the selected configuration or the selected connection type, and can be modified if desired.

Insertion according to DAST

The data for the typified Steel Engineering connections according to DSTV/DAST are in stored in tables in HiCAD: To apply the data for the related parts such as plates, screws etc. from these tables, select the connection type first.

To do this, click the symbol and select the desired connection in the displayed dialogue window.

Example

Click the Extended button to show more data of the possible connections. You can set one or several filters (Bolts+Screws, Strength...) to limit the selection options. Select the desired option and close the window with OK. The designation of the selected DAST connection will then be shown in the input field.

After the selection of the DAST connection, the contents of the tabs will be adjusted accordingly. Settings that are not possible for the selected connection will be greyed out.

User-defined insertion

For user-defined insertions you can also use the settings from the DAST tables as predefined values and modify them if desired. If you have changed any settings on the tabs that do not correspond to the preset values of the selected DAST connection, this will be indicated by a symbol next to the DAST designation. If you move the cursor. When you move the cursor over the symbol, a message will be displayed, e.g.:

To restore the settings to defaults, click the symbol. To remove the assignment to the DAST presettings, e.g. because you prefer a user-defined connection, click the symbol.

Configure front plate connection

The configuration of the front plate connection takes place via the tabs of the dialogue window:

• Process,
• Front plate,
• Boltings,
• Bore grid,
• Galvanization,
• Weld seams and
• Filler plate.

Process

Depending on the fitting situation the beam to be inserted will be notched automatically. The options for the notches can be specified on this tab. Registerkarte fest.

Process tab

 

Upper/lower notch

Required are first the distance between the end of the beam to be notched ad the web of the target beam. The horizontal and the vertical distance can be specified separately for the upper notch and the lower notch. Which distance is specified here will be determined via the graphical selection boxes.

Horizontal distance to		Vertical distance to
	Web of target beam		Outer edge of notched beam
	Flange of target beam		Inner flange edge of target beam
	End of notched beam		Outer flange edge of target beam

You can apply the settings for the upper notch by clicking on the icon.

 

Orientation

The orientation can be parallel to the web and relative to the target beam or the notched beam.

	Parallel to web / Relative to target beam
	Parallel to web / Relative to notched beam

 

Corner processing

You can choose between the following two options:

• Bore out and
• Fillet.

If the Dimensions acc. to DAST checkbox is active, the next higher values from the "DSTV Typified Structural Steel Engineering Connections" (Volume 1, "IK Notches" chapter) will be used for the notch length, notch height and the fillet.

Front plate

On this tab you specify the type, appearance and size of the plate, and the alignment of the plate in relation to the beam.

Front plate tab

Boltings

Here you specify the bolting, i.e. the bolt type, diameter etc. Click on the icon and select the components of the bolting. The default setting is DIN EN ISO 4014-M16-5.6 / M16 (⌀ 17,5). Proceed in the same way as you would do with the Steel Engineering Bolting function.

The bolting will only be inserted if the Fit checkbox is activated.

If you want to Invert the bolting direction, activate the same-named checkbox.

Boltings tab

If you want to insert reinforcement plates, activate the Create checkbox. If you want to connect the plates (if possible), activate the Connect plates if possible checkbox. Corners of connected reinforcement plates can also be filleted if desired: Activate the Fillet corners checkbox and enter the fillet radius.

Enter the distance to the bores to the edges of the reinforcement plate, click and choose the type of the plate from the catalogue.

Usage and Assignment

In the Usage field you can specify which usage is to be assigned to the assembly of the 1st beam.

The bolting is inserted as a Bolting group. Next to Assignment you can choose whether this Bolting group and the reinforcement plates are to be assigned to the assembly of the 1st beam or are to be inserted as Loose parts.

If you activate the Assembly (1st beam) option, the Bolting group and the reinforcement plates are assigned to the assembly of the 1st beam.

If you activate the Loose partoption, the Bolting group will be inserted as a separate assembly on the same level as the assembly of the 1st beam. The reinforcement plates will be assigned to a structure assembly called Loose parts that also contains filler plates. This structure assembly is also located on the same level as the 1st beam.

(1) Bolted connection, (2) Reinforcement plate, (3) Filler plate

Please note that the settings for the Usage and the Assignment must be made before the creation of the assembly structure of the connection. After clicking the Preview button, and also after insertion of the connection, a change of these settings will no longer be possible.

Notes on hollow profiles:

If the beam to which the connection is made (2nd beam) is a hollow profile, the Boltings tab will contain additional options:

• Through
  If this checkbox is active, the bolt will run entirely through the 2nd beam.
• Create mounting aperture
  If this checkbox is active, the bolt will run only through the first surface of the 2nd beam. In the second surface, a mounting aperture with the specified diameter will be created.

If both checkboxes are deactivated, the bolt will only run through the first surface of the beam, with no mounting aperture being created in the second surface.

(1) Beam to be connected, (2) Target beam to which the connection is to be made, (3) Through, (4) With mounting aperture, (5) Both checkboxes deactivated

Bore grid

The bore grid determines the pattern of bores for the front plate.

Bore grid tab

First you need to choose a reference for the Horizontal and Vertical settings. Further value inputs depend on the selected reference.

Galvanization

Here you can choose whether you want to apply bores for a zinc plating to the front plate. Activate the corresponding checkboxes and enter the desired diameter. In addition , you can specify a minimum distance of the bores to the flange and to the web.

Galvanization tab

Weld seams

On this tab you can choose, by activating the corresponding checkboxes, which weld seams are to be created:

• A circumferential seam,
• Weld seams on particular edges, or
• all weld seams.

For each edge you can select the type of the thickness designation, the weld seam thickness the weld seam type and the inspection category. If you want to use the same settings for all edges, click the Equate symbol.

Weld seams tab

If you want to insert filler plates between the front plate and the 2nd beam, you can specify the number, the type and the size of these plates on the Filler plate tab.

Filler plate tab

The following geometries for filler plates are available:

• One-piece, insert left,
• One-piece, insert right,
• One-piece, insert at top,
• One-piece, insert at bottom,
• One-piece, drilled,
• Two-piece, insert horizontal and
• Two-piece, insert vertical.

Depending on the selected geometry type, enter the required distances and the hole clearance. The hole clearance always refers to the bolting.

(1) Bolt diameter, (2) Two-piece filler plate, (3) Hole clearance

Beneath Manage you can specify the number of filler plates.

For each filler plate, select the desired plate type in the catalogue . Specify, by activating the corresponding checkboxes, whether the filler plate is to be pre-planned or not. If a filler plate is pre-planned, the 1st beam will be shortened by the thickness of the filler plate. Non-pre-planned filler plates will be created next to the connection.

Activate the All checkbox to set all filler plates to Pre-planned in one step.

Please note that non-pre-planned filler plates will be shown in transparent representation in the drawing, i.e. they will be assigned to Layer 40.

Non-pre-planned filler plate

Filler plates are not assigned to the assembly of the 1st beam, but are placed in a separate structure assembly with the name Loose parts. Also, the usage Filler plate will be assigned to filler plates.

If the bore grid is too narrow, preventing the insertion of the filler plates, the connection will not be created, but the failed operation will be recorded in the feature log:

You can then double-click the feature and correct the settings.
