PEB Member

The PEB Member plugin allows you to create a PEB built-up member with multiple depths (up to 6), multiple webs (up to 5), and multiple flanges (up to 5). You can adjust any part property (web, flange) inside the PEB Member component to meet any PEB requirements.

How to locate

Installers are available at Pre-Engineered Building Tools for Tekla Structures version 21.0 and above.
For older versions, download at Pre-Engineered Building Tools old installers

After installation, the PEB Member plugin will be available in the Applications & Components.

Usage

Pick two points for start and end points. The tool creates a PEB member with default values between the picked points. 

PEB Member dialog box

The dialog box contains the following tabs:

• Parameters
• Parts
• Assembly

Image

 A standard attribute file comes with the installation and it is available in the attributes list. If the standard file is not loaded, select it from the list, and click Load. This loads all default values into the dialog box.

1. Number of depths

From this list, you can select the number of depths required. The dialog box shows an image of the selected option for reference.

Depth	PEB Member Type
2	Image
3	Image
4	Image
5	Image
6	Image

2. Start taper

Image	No taper at the end
Image	Auto taper based on the global Z axis (true vertical taper)
Image	Start taper manual input (negative values can also be given)

3. End taper

Image	No taper at the end
Image	Auto taper based on the global Z axis (true vertical taper)
Image	End taper manual input (negative values can also be given)

4. Start offset

You can maintain the start of the PEB Member at a given distance from the start point input.

5. End offset

You can maintain the end of the PEB Member at a given distance from the end point input.
         

 6. Depth alignment options

7. Rotation about member axis

Note: Arrow direction is pointing towards the outer flange. This allows you to manually enter an angle.

8. Depth definition

Depth is defined by Depth and Depth Locations (depth at a particular distance). If depth locations are empty, the total length of the member is equally divided and assigned to each depth except the first depth (D0). If you enter a value in some of the Depth Location text boxes, and leave the rest empty, the depth locations are maintained wherever defined, and the remaining length is divided equally and shared to the remaining depths for which depth locations are not given.

9. Provision to add flange offset value

If you keep the value zero or leave the text box empty, then after applying the connection and the member update, the flange is updated without a clash with the end plate.

If you enter a value other than zero, then after applying the connection and the member update, the flange offset you enter is used on the member. This is useful for entering a weld gap.

Parts

Image

On the Parts tab, you can define the outer flange, inner flange, and web. The concept used for all three is the same and for length, it is similar to defining Depth.
Below an example of defining the outer flange:
  

Image

Default values are used if you do not enter any values. For length, the value you enter is used as is. The remaining length values will be calculated as,
Default length value = (total input length – (sum of user input length values)) / no of length inputs not given by user

This default length value will be updated to each part length if you do not enter a value.

If plate profile name is default, it reads from Menu>Settings>Options>Components>ProfileNames>Plate. The same profile name is applicable for stiiffeners also.
Similarly for folded plate, folded plate profile name is default, it reads from Menu>Settings>Options>Components>ProfileNames>Folded Plate.

Tips

• Zero thickness / Zero Width Functionality You can enter ‘zero’ thickness or ‘zero’ width for parts, see below for an example. With this feature, you can create a member that does not have a flange of a particular length. Keep Length empty for a default adjusted length.

PEB Assembly attributes
For a PEB assembly, a PEB tab is added to the PEB assembly properties dialog box. You can define the sizes of material for the outer flange, inner flange, and web.
