Project: HiCAD Steel Engineering

Angle Connection, One-Sided

"Civil Engineering functions" docking window > Steel Engineering > Connections > Front side to web/flange side > Angle > Angle connection, one-sided (1305)

Use this function to connect two beams by flexible angle steels. The connection can be user-defined or according to DAST. For DAST connections you can choose between

• Type IW connections
  The beam to be connected will be shortened, lengthened and/or notched automatically if required.
• Type IG connections
  The beams abut and will be connected by means of angle steels.

The function can be applied to parallel and perpendicular flanges.

Angle connection, one-sided

Proceed as follows:

1. First, select the beam you want to connect (allowed are I-, L-, U-, T- or Z-beams).
2. Then, select the target beam to which the connection is to be made (allowed are I-, L-, U-, T- or Z-beams).
3. The Angle connection, one-sided (1305) dialogue window will be displayed.
   

Angle connection, one-sided (1305) dialogue window

The configuration of the angle connection takes place via the tabs of the dialogue window.

Click the Preview button to display a preview of the connection, based on the current data. If you want to correct the data, make the desired modifications and click Preview again to update the preview. Click OK to insert the connection with the specified data, and the dialogue window will be closed. Click Cancel to close the dialogue window without inserting/changing the connection.

Click the symbol to display information on the previously identified beams, e.g. type, material, dimensions, etc. Data input and changes are not possible here.

Selected parts

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.

It depends on the settings on the Bolting tab how the angle connection will be inserted into the part structure.

User-defined insertion or insertion according to DAST

The insertion of the angle 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 angle steel, plates, screws etc. from these tables, select the connection type IW or IG first, by clicking on the appropriate symbol. HiCAD will then display a selection of possible connections. if you want only DAST-conform connections to be displayed, activate the corresponding checkbox beforehand. If the checkbox is not active, the non-conform connections will be highlighted in a different colour.

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 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

If you want to insert the connection without using the DAST tables, the DAST input field must be empty.

You may need to remove the assignment to a DAST table.

Configuration of the angle connection

The angle connection is configured via the tabs:

• Process
• L-bracket
• Bolting
• Bore grid

Process

Here you specify the distance between the end of the beam to be connected and the web of the target beam. Furthermore, you specify, via the Mode selection list, the way in which the connection is to be made.

Process tab

You can choose between two Modes for the connection:

L-bracket

On this tab you define the angle steel of the connection, the so-called "L-bracket". You can also specify whether you want to use two L-brackets, only the left one, or only the right one for the connection.

L-bracket tab

Boltings

Here you define the bolting, separately for the two beams. First, specify the components of the bolting, e.g. the type of the bolt, the bore diameter etc. click the symbol to specify the components of the bolting. The procedure is the same as with the normal Steel Engineering bolting function.

In addition, you can specify:

• whether the bolting is to be inserted (Fit),
• whether the bolting direction is to be inverted (Invert), and
• the production type for bores (Site or Workshop).

If you select the Workshop production type, you can click the symbol to select the Usage from the same-named catalogue. The default setting is Girder (beam) assembly (for example, part annotation in workshop drawings can take place depending on usage). If a usage has already been assigned to the assemblies of the beams, 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.

Bolting tab

A maximum of 3 Bolting groups are created for this angle connection. The assigning of these bolting sets depends on the settings on the Boltings tab.

If you have chosen the production type Workshop for one of the beams, you can select beneath Assignment, by activating the corresponding option, whether the bolting groups of this beam are to be assigned to the assembly of the beam, or to a structure assembly called Loose parts on the same level as the assembly of the beam. The L-brackets of the connection are assigned to the assembly of the beam with the production type Workshop.

If you have selected the production type Site for both beams, the L-brackets and the bolting groups will be assigned to a structure group called Loose parts.

Bore grid

The bore grid determines the arrangement of the bores for the angle steel.

Horizontally, the grid can be specified separately for the beam to be connected and the target beam for the connection. For each situation you need to specify the Number of bores, a Reference and the Distances between bolts.

For the vertical settings, also enter the number of bores and specify, via the corresponding selection box, whether you want the number of bores to be identical for the 1st beam and the 2nd beam, or if you want one fewer row for one of the beams. In addition to the reference and the distance to the reference you can select an Offset to the reference edge.
