1. Purpose and description

This is a prototype extension that creates a bent plate connection for 3-plate tapered beam to beam scenarios -- perpendicular, sloped and skewed. Assuming that the plates are beam type plates and the web plate is designated as the main part of the assembly

2. System requirements

Environments: Default, US Imperial, US Metric
Languages: English

3. Installing PEB Beam To Beam Bent

To install the application:

Close Tekla Structures (if running)
Download the installer (MSI or TSEP) from Tekla Warehouse ( also potentially the TSEP File Dispatcher Launcher )
Run installer or import TSEP. (see how to Import a .tsep extension )
Start Tekla Structures
Create a new model or open an existing model
Open the Applications and components side pane and a new icon with the extension's name should be found within Ungrouped items or US Extensions

4. Using PEB Beam To Beam Bent

To use the extension:

Select icon in Applications and components side pane
Right-click to open the properties settings;
Set the properties as desired
With the Select components or the Select objects in components selection switch active
Select primary (supporting) 3-plate assembly
Select secondary (framing) 3-plate assembly

5. Interface

This tool adheres to Tekla Structures general user interface options where possible where it differs is highlighted and explained below.

Secondary pull-back framing distance
Bend radii
Sloped framing end cut options - Square or Aligned
Skewed framing end cut options - Square or Aligned
Bent plate position options - Nearside, Farside or Both
Secondary attachment options - Bolted or Welded
Bolt and plate alignment options

There are six options on how plates/bolts follow orientation of either primary or secondary member. Ends of plates away from joint center are all square to the plate, not cut vertical (chopped).

Option	Primary Plate	Secondary Plate	Bolts in Primary	Bolts in Secondary
1	Secondary	Secondary	Primary	Secondary
2	Secondary	Secondary	Secondary	Secondary
3	Primary	Secondary	Primary	Primary
4	Primary	Secondary	Primary	Secondary
5	Primary	Primary	Primary	Primary
6	Secondary	Secondary	Primary	Primary

Notes:

If the plate/bolt orientation option is set to option 1, 2, 5,or 6 and depending on slope, skew, plate thickness and bend radius, the bolts are offset from the original calculated position (from dialog values) up or down along the bend axis an exact distance to accomodate the bent plate curvature. This is required to provide a final result that is flat when unfolded.
When using plate/bolt orientation option 5 and both nearside and farside plates in combination the secondary side of the bent plates will have different orientations as option 5 dictates that the primary plate's flat x-axis is rotated around the bend asis to the plane of secondary and will give a different angle along the secondary beam for each side.

5.3 Bolts Positions

Bolt group positioning options - Aligned To Secondary or Aligned to Primary

Notes:

Primary bolt locations are measured from the line resulting from the primary and secondary web center plane collisions as it intersects the top plane of the primary beam flange.
Calculated bolt edge distances should not be less than the dialog values anywhere but may be greater than the dialog values due to the merged plate geometry effect.
The primary plate and secondary plates are independently sized based on bolt location and edge distances first, then each plate is copy-rotated around the bend axis and the superimposed edges are analyzed against each other.
The largest edges are used in the merge process so that the final bent plate geometry will be large enough to not violate the edge distances of either plate.

6. Additional information

This is a prototype extension
3-plate beam assembly must comprise of beam plates with the main part being the web plate
Plugin may fail to insert with extreme slope or skew conditions.
