 2 Creating System
Connections

In this lesson This lesson introduces the basics of creating system connections in Tekla Structures.
You will learn how to:
• Create connections
• Work with connection properties
• Save the properties for later use
• Work with AutoDefaults, i.e. create rules to apply pre-defined connection properties
automatically

2.1 About System Connections

You can model connections quickly with the Tekla Structures system connections.
The greatest benefits of using system connections are:
• The connection properties can be saved with a particular name so that they can be used
later. These properties can then be used for all projects.
• When you modify a main objects profile in the model all of the connections to the object
are automatically modified at the same time.
• If you select options such as edit, copy, or mirror, all connections are automatically
included. The connections that are copied or mirrored are exactly the same as the
originals. The same applies to plates and bolts.
• With AutoDefaults you can create rules defining when to use different connection
properties.
All available system connections are located on the connection toolbars, which can be found
at the right of the main window.
When applying a connection that you are unfamiliar with, accept the default properties and
create the connection. Then look to see what needs to be modified. This is usually quicker
than trying to set the values for the connection before seeing what the connection actually
creates.

Check Clashing of Steel Structures

In Chapter 1 we created a model of a small industrial structure. To complete the model we
will need to connect the parts. Before creating the connections usually all of the members in
the model collide with other members.
By using the Clash check command we can check which parts in the model collide. We will
run a clash check now and then again after the connections have been applied.
Help: Modeling > Settings and tools > Querying objects > Clash check
Check clashing 1. Select all of the parts of the model by dragging an area select around the whole model.
2. Right-click and select Clash check.
Tekla Structures highlights the colliding parts in yellow and displays the clash check log in
the List dialog box. You can see that all of the parts in the model collide.

Select any clashing parts from the list and Tekla Structures highlights them in the model.

base plate.

2.3 Beam to Beam Web

Shear Plates
We will use the Shear plate simple (146) connection to make the beam to beam web
connections. The shear plate will be welded to the primary beam web and bolted to the
secondary beam web. We will use the connection both when the secondary beam is
perpendicular to the main member or at a skewed angle to the main member.
Create one shear 1. From the page 1 connection toolbar, double-click the Shear plate simple (146) icon.

Check the Connection
To make it easier to check the connection you created you can create views from different
sides of a selected connection. In the view the work area is closely fitted around the
connection.
Create connection To create component basic views:
basic views
1. Select the connection symbol.
2. Right-click and select Create view > Component basic views, four basic views (front,
top end and perspective) appear.

 Now we will accept the created connection’s with the default properties.
Create the rest of With the connection’s applied properties, create shear plate connections to all of the rest of
the shear plates the beam to beam conditions.

2.4 Beam to Column Web

We will use the End plate (144) connection to make the beam to column web connections.
For the double sided beam to column web connections we will use the Two sided end plate
(142) connection. That connection uses only one bolt group to go through all three parts.

Copyright © 2004 Tekla Corporation TEKLA STRUCTURES BASIC TRAINING 11

Creating System Connections
 We will then make the wall brace to column connections with Tube gusset (20). The
connection uses a gusset plate to connect the beam to the column. Connection plates welded
to the end of the braces will be bolted to gusset plate.

End Plate
We will now use the End plate (144) connection to make all of the beam to column web
connections using the default connection properties. We will modify the properties later with
AutoDefaults.
Create end plates 1. On the page 1 connection toolbar, double-click the End plate (144) icon.

2. Make an end plate connection at every beam to column web condition where there is
only one secondary beam coming to the column web.

2.5 Beam to Column Flange

We will now create End plate (144) connections to all of the beam to column flange
conditions by using the default properties.
Then we will edit one of the connection’s properties. Instead of modifying the rest of the
connections with the new properties, in the next section, we will create AutoDefaults rules to
define when certain properties will be used.

2. Create connections at all of the beam to column flange framing conditions.

Change the Number of Bolt Rows and Save the Properties

We will now change the number of bolt rows to eight when the secondary beam is IPE600.
We will then save the new properties with a specific name so that we will be able to use them
in AutoDefaults.

6. Use Save as to save the properties as 7_bolt_rows.

2.6 Create AutoDefaults Rules

With AutoDefaults you can create rules defining when to use different pre-defined
connection properties. When the connections need to be modified (for example changing the
beam size), Tekla Structures automatically redefines the connection properties using
AutoDefaults rules defined by you.

New Rule Group: Industrial Building Rules

We will now create a new AutoDefaults rule group named Industrial building rules.

18 TEKLA STRUCTURES BASIC TRAINING Copyright © 2004 Tekla Corporation

Creating System Connections
 This rule group could include all the rules needed to define when to use certain pre-defined
connection properties for the entire project.
Help: System > AutoConnection > AutoDefaults setup > AutoDefaults setup
We will now define two simple rules for the End plate (144) connection.
1. When the secondary is an IPE500, the end plate connection will have 7 bolt rows.
2. When secondary is an IPE600, the end plate connection will have 8 bolt rows.
When the secondary is neither of the above (IPE500 or IPE600) the default rule will be met
and the standard properties will be used.

Create new rule 1. Click Setup > AutoDefaults… to open AutoDefaults setup dialog box.
