1 Getting Started

Introduction Once you have created a frame of parts in your Tekla Structures model, you will

need to connect those parts to complete the model Tekla Structures contains a wide range of components that you can use to automate the process of creating a model

This chapter explains the basics about components - what they are and how to create them using Tekla Structures We will begin with the basic concepts, fol-lowed by a general description of components properties Finally, we will show you how to use components in practice

Contents This chapter is divided into the following topics:

• Basics (p 5)

• Using components (p 14)

• Defining parts and plates (p 18)

• Defining bolts and welds (p 22)

• AutoConnection (p 31)

• AutoDefaults (p 34)

1.1 Basics

Introduction Components are tools that you can use to automatically create the parts, welds,

and bolts required to connect parts They are linked to main parts, so, when you modify a main part, the associated component also changes

Benefits The main benefits of working with components are:

1 You can save the properties of a component using an easily-identifiable name and keep it for future use For example, you could save the properties

of a W12x65 column base plate connection as W12x65.j*, and use it for eral projects

sev-2 When you modify the size of a profile, Tekla Structures automatically fies the relevant components

modi-3 When you use Copy or Mirror, Tekla Structures automatically includes all the associated components

Component concepts

Components are tools that automate tasks and group objects so that Tekla

Struc-tures treats them as a single unit Components adapt to changes in the model, so that Tekla Structures automatically modifies a component if you modify the parts

it connects

This is an example of how to apply a connection:

1 Pick the main part

2 Pick the secondary part

To see information about the connection, click the connection symbol

The connection matically creates the required parts, fittings, bolts, etc

auto-Component types Components have the following subtypes:

Tekla Structures contains a component catalog, where you can:

• search for components using name, number, or keywords

• start creating a component

• view component properties

• collect your own favorites

• define keywords for components

• import/export components

Connections Connect two or more parts, and

create all the required objects (cuts, fittings, parts, bolts, welds etc.)

Two-sided clip angle, bolted gusset

Macros Automatically create and

assemble the parts to build a structure, but does not connect the structure to existing parts

Macros can include tions and details

connec-Stairs, frames

Details Add a detail to a main part A

detail is only connected to one part When you create a detail, Tekla Structures prompts you

to pick a part, followed by a point to locate the detail

Stiffeners, base plates, lifting hooks

To open the component catalog, use the keyboard shortcut Crtl + F, or click the Search component icon on the component toolbar (shown below)

Example This example shows the search results for the search term "Part":

Symbols The first column in the catalog indicates the component types with following

symbols:

System nents have blue symbols

Custom nents have yel-low symbols

compo-Double-click the name to set the properties and create the component

To sort a column, click the header cell

Symbol Component type

System connectionsSystem detailSystem macroCustom connections and seamsCustom details

Pop-up menu Right-click the list to open a pop-up menu containing the following commands:

Introduction You will find all the available components on the component toolbars, located to

the right of the main Tekla Structures window If the toolbars are not visible, click Window > Toolbars > Components to display them

Usage This is an example of toolbars and the functions they contain:

Component dialog box

The component dialog box is in two sections

Upper part You use the upper section of the dialog box to save and load predefined settings,

see Save, Load, Save as, Help in the Modeling manual For some components,

it also contains buttons for accessing the bolt, weld and DSTV dialog boxes

Initiates the last connection you used

Component icons

Toolbar ber or symbol

num-Use the arrows to flip through the toolbars

to check which ponents are available

com-Opens nent catalog

compo-For information on handling the saved properties, see Component properties files in the System manual

Lower part The lower section of the dialog box is divided into tabs This is where you define

the properties of the parts and bolts that the component creates The most mon tabs that appear here are:

com-• Picture illustrates the component It shows just one example, but you

can usually use one component in many situations

• Parts is where you define the properties of the parts the component

creates

• Parameters is where you set parameters to control the component (for

example, for stiffeners, end plates, chamfers, etc.)

• Bolts is where you define the number of bolts and their edge distances

• General is where you define the direction of the connection or detail

and AutoDefaults rules

The green symbol

indi-cates the correct direction

for the connection or

detail

The parts the nent creates appear in yellow

compo-The parts you select appear in blue

2 A point in the main part to show the location of the detail.

Macros The default picking order for a macro is:

1 Pick one to three point(s) to show the location of the objects the macro ates

cre-Up direction

The up direction of a connection or a detail indicates how the connection is

rotated around the secondary part, relative to the current work plane If there are

Pick the parts in the order shown in the Picture

The Picture tab in the dialog box shows the up direction Tekla Structures will use Tekla Structures also indicates the up direction in the connection symbol:

Manually defining

up direction

To manually define the up direction:

1 Double-click the connection symbol to open the connection dialog box

2 On the General tab, change the x, y, or z direction Try positive directions first

3 Click Modify to use the new values

Automatic and default properties

Some connection dialog boxes contain list boxes that show property options as graphics You can select system defaults, AutoDefaults, or have Tekla Structures automatically set the properties

System default

properties

If you leave fields in connection dialog boxes blank, Tekla Structures uses the system default properties Manual entries, default, automatic and properties in the joints.def file, all override these system defaults You cannot change system default properties

To have Tekla Structures use a default property in a connection, select the option marked with this symbol.

If you use AutoDefaults for the tion, Tekla Structures uses the property defined in the AutoDefaults rules If you are not using AutoDefaults, Tekla Structures creates the connection using the system default property

connec-Using AutoDefaults

(p 34)

To have Tekla Structures automatically determine which option to use for a property, select the option marked with this symbol

Example, Boomerang bracing tion (60):

Use the Automatic option

on the Gussetbolt1 tab to have Tekla Structures determine how the clip angle

is connected to the gusset plate and beam

Up direction Rotates the connection around

the secondary part or detail around the main part

The fields next to the image define rotation angle around the x- and y-axis of the sec-ondary The upper one is for y- and the lower one for x

1.2 Using components

Introduction This section explains how to use components It also includes an example

Creating components

You create different types of component in different ways For example, you

pick existing parts to indicate which members a connection or a detail is attached to You need to pick points to indicate the location or length of a detail

or a macro See also Picking order (p 11)

When you create connections, Tekla Structures prompts you to pick the primary part (the part secondary parts connect to), then the secondary part(s) For an example of using a connection, see Example (p 15)

Class A number given to all parts

the connection creates You can use class to define the color of parts in the model

Colors

Connection code Identifies the connection

Tekla Structures can display this connection code in con-nection marks in drawings

AutoDefaults Rule Group

Automatically sets connection properties according to the selected rule group To switch AutoDefaults off, select the rule group None

Using AutoDefaults

(p 34)

AutoConnection Rule Group

Automatically switches the connection to another accord-ing to the selected rule group

Status Tekla Structures uses different-colored connection symbols to show the status of

connections and details, as shown below:

Example

When applying a component that you are unfamiliar with, accept the default properties and apply the component Then look to see what needs to be modified This is quicker than trying to set the values for the component before seeing what the component actually creates

This is an example of how to generate an end plate connection The End plate

(144) connection connects two beams, or a beam to a column, using a bolted end

plate

To create the end plate connection:

1 In the Component catalog (p 7), type "144" and click Search

2 Double-click the End plate (144) line Tekla Structures displays the nent dialog box and starts the End plate (144) command

compo-3 Tekla Structures prompts you to pick the main part (column) and then the secondary part (beam) Tekla Structures creates the connection

Green Connection created

up direction is not ate See Up direction (p 11)

appropri-4 Select the next main part or interrupt the command.

If you need to change the number of bolts or plate dimensions, for example, you need to modify the component For more information, see Modifying compo- nents (p 16)

If you use incorrect properties, Tekla Structures may fail to create the component (see Creating components (p 14))

Modifying components

To modify a component, double-click the component symbol in the model The component dialog box appears This is where you modify the component proper-ties

You can also indicate which connections and details are affected by the tions:

modifica-• Modify connection type: If you have selected several connections

details, clicking the Modify button modifies all the selected tions and details irrespective of their type If the connection type is not the same as in the dialog box, Tekla Structures changes the con-nection type

connec-• Ignore other types: Tekla Structures only modifies connections and

details of the type shown in dialog box

If you have Select component swicthed on , you do not have to pick component symbol, but you can just pick any object belonging to a component This is the only method for selecting custom parts, because they do not have any symbol

Conceptual components

Conceptual components help create a smooth workflow from engineer to detailer Engineers do not have to consider fabrication details, they simply create conceptual components that look real The detailer then takes the conceptual components and creates fully-detailed components that include all the informa-tion needed for fabrication, such as assemblies, cast units, and reinforcing bars.The Tekla Structures configuration you have determines which components you can create:

Changing

component type

You cannot create conceptual components using the Steel Detailing, Concrete Detailing, or Full Detailing configurations, but they do include a tool that you can use to change individual conceptual components to detailed components.The Basic Design, Standard Design, and Engineering configurations also include

a tool to change individual detailed components into conceptual components

To change a conceptual component to a detailed component:

1 Select the component symbol

2 Click Tools > Change to detailing component

Changing part properties, such as changing the size of the main part, do not matically change the component type So someone using thte Basic Design con-figuration can change the model without automatically changing detailed components back to conceptual ones

Conceptual

Fully detailed component contains part and assembly numbering fields and creates needed assemblies, cast units and reinforcing bars

Tips on working with components

No component

created

If you have difficulty applying a component, check the status bar for prompts For example, you may need to click the middle mouse button to stop selecting parts, before Tekla Structures creates the component

Many parts found If you are applying a connection that only allows for one secondary member, you

may see the message Many parts found on the status bar This means that Tekla Structures cannot determine which parts to connect You may have several parts

in the same location, or the view may be set too deep

Switch parts on/

off

If the component does not create the parts you need by default (for example, stiffener plates), look for a switch to turn them on If there is no switch, try enter-ing a value in the thickness field for that part (for example, on the Stiffeners tab)

If the component creates parts you do not need, look for the switch to turn them off If there is no switch, enter a zero (0) in the thickness field for that part

Entering valid

profiles

You need to specify profiles for some components If a component fails, try entering a valid profile

1.3 Defining parts and plates

Use the Parts tab to define the parts that Tekla Structures creates when you use a component

Default: Tekla Structures creates stiffeners or uses value retrieved from AutoDefaults

Automatic: Tekla Structures creates or omits ers depending on the situation in the model

stiffen-Tekla Structures does not create stiffeners

Tekla Structures creates stiffeners

Using the dialog box

Some components list all parts on one tab, others list parts on separate tabs as shown in the following examples

One Parts tab Where there is one tab, the label is usually Parts or Plates

Several Parts

tabs

Plates can also appear on separate tabs For example, in connection 56, Corner

tube gusset, the parts appear on both the Gusset and Tube diag tabs.

Dimensioning parts

Use the Parts tabs to dimension specific part types in components

To delete a part, enter zero (0) in the t (thickness) field

Enter the following dimensions for plates:

You do not have to enter these dimensions for every component type, as Tekla Structures determines the plate shape differently for different components For example, in end plate connections, Tekla Structures calculates width and height using the number of bolts and bolt edge distances Click Help in a component dia-log box to check which dimensions you need to enter

Beams

To specify a library or parametric profile to use for beams:

• Enter the profile name

• Or click , and select a profile from the profile catalog

Part position number

Use the Pos_no field to enter the part position number for each part the nent creates This overrides the settings on the Setup > Options > Preferences tab

compo-Specify a prefix and a start number, as shown below.

Some component dialog boxes have a second row of Pos_no fields for you to enter the assembly position number

Using the Preferences tab

To set the default prefix and start number for all the parts that components create, click Setup > Options > Preferences tab You define different prefixes and start numbers according to the part’s relationship to other parts in the component Separate the prefix and part number using the \ character (for example, p\1)

Defining materials

To define the materials for the parts that components create, click against the

Material field Tekla Structures opens the Select material dialog box Click a

mate-rial type, then click the matemate-rial to use for the part

Using the Preferences tab

To set the default part material for the parts that components create, click Setup >

Options > Preferences tab > Part material Tekla Structures uses this default if you

leave the Material field blank in the component dialog box when you apply the component

1.4 Defining bolts and welds

Use the Bolts or Welds tabs to define which bolts, assemblies, and welds to use in specific components

Using the Bolts tab

This illustration shows the properties you can set in the Bolts tab of component dialog boxes:

Edge distance

Number of bolts

Bolt spacing (horizontal)

Bolt spacing verticalNumber of boltsEnter bolt order number of bolt

-to delete

Check bolt ponents to include (bolt, washer, screw)

com-Slotted to create

Bolt group pattern

Defining bolts

Use the following fields on the Bolts tab to specify the type of bolts to use in vidual components:

indi-Increasing bolt length

To allow for additional material thickness, increase the length of the bolt on the

Bolts tab For example, you could use this for painted parts

Tekla Structures uses this value in bolt length calculation See Bolt length lation in the online help

bolt and bolt assembly catalogs in the online help

Bolt standard The bolt standard to use inside the component Must be

defined in the bolt assembly catalog

Tolerance Gap between bolt and hole

Thread in mat Indicate if the thread can be inside bolted parts when using

bolts with a shaft Has no effect if using full-threaded bolts

Site/Workshop Location where bolts should be attached

Enter extrabolt length

Number of bolts and spacing

Use the Bolts tab to specify the number of bolts and bolt spacing, both tally and vertically

horizon-Enter the number of bolts in the shorter field, and the spacing between bolts in the longer field, as shown below Use a space to separate bolt spacing values Enter a value for each space between bolts

Example For example, if there are 3 bolts, enter 2 values

The settings above result in this bolt group layout:

Bolt group orientation

Some connections include the following options on the Bolts tab to orientate bolt groups:

Number of bolts

Bolt spacing

Square

Staggered in the direction of the secondary part

Sloped in the direction of the secondary part

Bolt group pattern

For some components you can select different bolt group patterns You have the following options:

Edge distance

Edge distance is the distance from the center of a bolt to the edge of the part Enter top, bottom, left, and right edge distances on the Bolts tab A dimension line on the illustration shows each dimension

Option

Edge distance dimension line

Enter edge distances here

Vertical bolt position

Use these options to indicate how Tekla Structures measures vertical dimensions:

Top Upper edge of secondary part to

You can also use the Bolt command to modify bolt groups after creating nents

compo-Deleting bolts

To delete bolts from a bolt group:

1 Double click the component symbol to open the component dialog box

2 Go to the Bolts tab

3 Check Delete

4 Enter the bolt number(s) of the bolt(s) to delete, separated by a space Bolt numbers run left to right and top down

5 Click Modify to change the selected component

6 Click OK to exit the component dialog box

For some components you can specify which parts have slotted holes using the Bolts tab For example, Clip angle (141), Shear plate simple (146)

Slotted hole length =

x or y dimension +

Bolt size + Tolerance

Example You start with this bolt group:

You enter the following bolt numbers:

The bolt group now looks like this:

Defining bolt assemblies

On the illustration on the Bolts tab, check the pieces to use in the bolt assembly (bolt, washers, and nuts)

To change the bolt assemblies in the current component:

1 Click the component symbol to select it

2 Check the pieces to use

3 Check Effect in modify

4 Click the Modify button

To define the properties of the welds Tekla Structures uses in a component, click the Welds button in the component properties dialog box Tekla Structures dis-plays the appropriate weld dialog box

The illustration identifies each weld using a number For each weld, use row 1 to define the arrow side of the weld, and row 2 for the other side

See also Welds in the online help

1.5 AutoConnection

Introduction Use AutoConnection to automatically select and apply connections with

pre-defined properties to selected parts Use AutoConnection to have Tekla tures automatically create similar connections for similar framing conditions

Struc-Using AutoConnection

Use AutoConnection to have Tekla Structures automatically create connections

using a predefined set of rules, or rule group.

Creating

connections

To create connections using AutoConnection:

1 Pick the parts to connect

2 Click Detailing > AutoConnection to display the AutoConnection dialog box

3 Select a rule group in the first list box on the Rule groups tab as shown below

4 Click the Create connections button

When you use AutoConnection, Tekla Structures ignores the properties in the connection dialog boxes and creates connections using the properties defined in the rule group Tekla Structures does not modify existing connections

You can change the properties of connections you create using AutoConnection

Additional

options

Use the options on the Advanced tab to indicate which rule groups you want to use for each Framing condition (beam to beam web, beam to beam flange, etc.) You also have the option not to apply a rule group, or to apply a specific connec-tion

Rule group for AutoConnection

Rule group for AutoDefaults

Example You can use a rule group for all framing types other than beam to column flange,

and indicate a particular connection to use for that framing type

Options Use Connection selection to indicate your preferences for each framing condition

You have the following options:

Use Parameters selection to indicate which connection properties you want to use The options are:

None Tekla Structures does not create a connection

AutoConnection Tekla Structures applies the connection defined in

the rule group you have indicated in the first list box on the Rule groups tab

A named connection Click Select to pick from a list of available

connec-tions Click a connection, then OK

Tekla Structures creates the connection you specify using the default properties See Automatic and default properties (p 12)

AutoDefaults Tekla Structures applies the properties of the rule

group you have indicated in the first list box on

Rule groups tab.

No AutoDefaults Tekla Structures applies the default connection

1.6 AutoDefaults

Introduction Use AutoDefaults to automatically apply connections When you use

AutoDe-faults, Tekla Structures automatically creates connections with predefined erties

prop-For example, you can use AutoDefaults to automatically adjust the thickness of each base plate you create, according to the primary part profile If the primary part profile changes, Tekla Structures will also automatically adjust the thickness

of the base plate

Using AutoDefaults

With AutoDefaults you can have Tekla Structures apply connection properties

using a predefined set of rules You can use AutoDefaults together with Connection to define connection properties, or separately to define the properties

Auto-of a single connection

To use AutoDefaults for a single connection:

1 Open the connection dialog box

2 On the General tab, select a rule group (the rule group cannot be None)

3 On all the tabs, set the fields that you want AutoDefaults to override to

Default by selecting the options marked with the arrow symbol )

4 Click Apply to create the connection using AutoDefaults

To quickly set all the fields in a dialog box to Default, load

<Defaults> in the connection dialog box.
