Project: HiCAD Steel Engineering

Front Plate Connection to Flange

"Civil Engineering functions" docking window > Steel Engineering > Connections > Front side to web/flange side > Front plate > Front plate connection to flange (2330)

Use this function to connect two beams via a bolted front plate connection. The connection can be made to the web or to the flange - with or without filler plates. In contrast to the connection 2320 the connected beam will not be automatically notched. Furthermore, you have the option to insert stiffeners between the flanges of the beam to which the connection is to be made.

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) anzuschließendes Profil, (2) Profil, an das angeschlossen wird, (3) erzeugter Anschluss mit Steifen

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.

	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
	The settings in the dialogue window can be saved as Favourites and reused at any time. To do this, click on the at the bottom left of the window to activate the context menu. More about Favourites management can be found in the Manage Favourites topics of the HiCAD Basics Help.

Please note:

• The front plate and the weld seams will be assigned to the assembly of the beam to be connected (1st beam). The stiffeners and the corresponding weld seams will be assigned to the assembly of the 2nd beam. Filler plates will not be assigned to this assembly, but will be placed in a separate structure assembly called Loose parts.The assigning of boltings and 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.

• If a DAST connection is changed, HiCAD checks whether the connection is still DAST-compliant. If this is not the case, the DAST selection field will be marked with the symbol. If you point to this symbol with the cursor, a corresponding message is displayed.

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 firs.

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. 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.

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.

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. 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:

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

Stirnplatte

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

Stiffeners

The connection can either be created with or without stiffeners between the flanges of the 1st beam. You distinguish between 1st stiffener, Middle stiffener and 2nd stiffener.

Stiffener tab

If you want to insert the stiffener, activate the Insert checkbox and click the icon to select the stiffener type from the catalogue.

Further parameters are as follows:

If you use the All equal button on the Stiffeners tab to apply the settings to all stiffeners, please note that the placing of the stiffeners will be automatically mirrored in the process. For instance, if you have placed the 1st stiffener on the Front side, the 2nd stiffener will be placed on the Back side when you call theAll equal function.

Important:

If the creation of the middle stiffener is not possible due to structural aspects, this will be indicated in the dialogue window by means of the symbol. When you move the cursor over the symbol, an explanatory message will be displayed.

Example - Middle stiffener not possible

Bolting

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.

Reinforcement plates - Connected plates (left) and individual plates (right)

Usage and Assignment

The bolting is inserted as a Bolting group. Next to Assignment you can specify to which assembly the boltings and the reinforcement plates are to be assigned.

If the Assembly 1st beam option is active, the boltings and the reinforcement plates will be assigned to the assembly of the 1st beam.

If you activate the Loose partoption, the Bolting group and the reinforcement plates - as well as the filler plates - will be assigned to a structure assembly called Loose parts.

In the Usage field you can specify which usage is to be assigned to the assembly of the 1st beam. If a usage has already been assigned to the assembly of the beam, the Overwrite usage checkbox can be used to specify whether the existing usage is to be kept or replaced by the usage type selected on the Boltings tab.

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

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 settings in the Bore grid tab determine 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 galvanization to the front plate and first profile. 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

Settings for the front plate

Determine where holes should be integrated by activating the respective checkbox and enter the requested diameter. In addition, you can enter the minimum distance of holes to flange and web.

Settings for the 1st beam

Here, you can choose via the checkbox Edit if either holes or web cuts should be integrated.

For inserting the web cuts, you determine the radius and the fitting position (top and/or bottom). For inserting the holes, you determine the installation position (top and/or bottom), the diameter as well as the distance to the web (Distance X) and to the flange (Distance Y).

On the left: web cuts, on the right: holes

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

For continuous HV and HY weld seams, enter 0 as the weld seam thickness.

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.
