Purpose and description

Apex Haunchcomponent object that represents a wedge-like structure that strengthens a beam at its end

connection connects two beams, tapered sections (PEB S94 Tapered Section) or 3 welded plates profile. Tapered sections or 3 welded plates can have web and flanges welded with any type of welds: part to part or polygon weld.

System requirements

Tekla Structures version: Not version specific
Environments:   All

Installing Apex Haunch

To install the extension:

  1. Download Apex Haunch installer package from Tekla Warehouse. For more information see Downloading an application from Tekla Warehouse.
  2. Install the file package.

Using Apex Haunch

To use the extension:

  1. Open a Tekla model.
  2. Click the Applications & components button   in the side pane to open the Applications & components cataloguser interface for displaying or modifying information in categorized lists

    For example, profile catalog and shape catalog are catalogs.

    .
  3. Search for Apex Haunch and then double-click to open it.
  4. Create two beams or tapered sections beams.
  5. For regular beams.
    1. Select the main part(1) part that exists in a building object and that determines the position number for the assembly or cast unit and the direction of assembly or cast unit drawings

      (1) Main part can be an assembly main part or a cast unit main part.

      (2) input part that the user selects first when creating a component

      (2) Connections and details always have a component main part.

      (supporting beam).
    2. Select the secondary part(1) part that exists in a building object and that is connected to the main part

      (1) Secondary part can be an assembly secondary part or a cast unit secondary part.

      (2) input part that the user selects after selecting the component main part when creating a component

      (2) A component can have none, one or more component secondary parts.

      (supported beam).
      The component is then created automatically.
  1. For tapered sections.
    1. Select the main part (flange or web of the supporting tapered section).
    2. Select the secondary part (flange or web of the supported tapered section).
      The component is then created automatically.

Note: The connection does not support any contour plates so make sure that the selected web or flange isn’t a contour platepart whose outline form the user defines by picking three or more points

The user can define the shape of the contour plate parallel to the work plane. The profile in use defines the thickness. The corners of the contour plate can be chamfered.

.

    and secondary or main part. Use this gap in connections of slightly curved or sloped beams to decide if the end angle is so small that the beam end can be left straight.
    If the actual gap is smaller than this value, the beam end is left straight.
    If the actual gap is larger, then the beam end is fitted to the end plate(1) part that represents a flat structure

Comments

by Keith Cooper

In tab 1: Part dimensions
Tolerance value and type - when this value is set, the plates are rotated as expected, but the rotation point is the top of the endplate.
This incorrectly shortens the rafter, making this connection unusable for us.
The plates should rotate around the intersection point of the top surface of the top flange of the rafters.

by Petri Hiilinen

Thank you for your comments!
We will add this request in to our defect management system.

Current way of working with only one gap value and rotation point being in the top of the endplate will prevent clashes between plates.
