Framed in beam with unequal existing members
If this is your first time with Anvil Forgeworx Pro™, please see our Quickstart documentation before proceeding.
All inputs will be made in the configurator screen; a walkthrough to this screen may be found here.

Input the following data:
- Vertical Hanger
- Overall Assembly Length = 144in
- Load = 5000
- Pipe Size = 24in
- Movement = 6in
Now that we have completed the steps required to define the hanger assembly, the support should look like:
The next set of inputs will configure the existing steel. Check the box under Existing Structure Types to tell Forgeworx you have an existing beam:
- Use Horizontal Steel
Now that Forgeworx knows there is steel above the hanger assembly, a beam running perpendicular to the pipe will appear. This is a piece of existing steel, and it is assumed that this steel is not provided by the support vendor. It will appear on the drawing, but is not included in the bill of material. Some of the options available under Existing Steel Parameters:
- Changing the profile to a tube or back to back channels.
- Size of the profile. Anvil has incorporated the 14th Ed. AISC steel library into Forgeworx.
- Weld size of the pipe structural attachment. A default minimum will be supplied. This size can be increased manually. Anvil does not return sizes for any other welds in Forgeworx. This will come in a later release.
The existing steel configuration can also be changed. We will change it to two beams running parallel to the pipe by:
- Existing Steel Configuration = 2 Parallel beams
- Distance Between Beams = 108
You should now see a typical configuration common in many applications with two beams running parallel to the pipe at 12' from center of pipe to bottom of steel. To finish adding information about our existing steel at this hanger location, do the following:
- Double Beam Configuration = Different Beams Equal Height
- Steel Profile 1 = 24X103
- Lateral Offset to Pipe Center = 30
We have shifted the center of the pipe relative to the left beam by 30” and increased its size. By entering a negative value for length,
the beams would have shifted to the right. Both the left and right existing steel profiles can be changed to any size available in the AISC 14th Ed. We could have also selected the option to have the two parallel beams be different heights.
The assembly at this point should look like this:
We have now supplied Forgeworx with all the information needed about the existing steel. We will now create a supplemental steel beam. Supplemental steel will be on the bill of material and is assumed to be supplied by the pipe hanger vendor. Create supplemental steel by checking the box.
- Create Supplemental Steel = True
Notice the supplemental steel snaps to the centerline of the left beam and not the underside of the right beam.
This is not an error. The default configuration for supplemental steel created with two beams parallel to and above the pipe is to be attached to both webs.
If the beam on the right was a larger size, this could still be a valid configuration.
In this release of Forgeworx, it is not possible to adjust the vertical position of the framed in beam. However, we can snap it to the right side by doing the following:
- Select supplemental steel in the tree view
- Supplemental Steel Configuration = Steel Between and Below Double Beam
The end result should look like this:
The size of the beam can be changed, as well as the profile to back to back channels or a tube. Angle clips are also supplied as a default. They can be turned off if required.
