Create steel joists

Steel joists, or bar joists, are a specific type of members used in the United States. They are simply supported secondary members that, in turn, support slab and roof loads. Steel joists are constrained to standard types specified by the US Steel Joist Institute, and standardized in terms of span, depth and load carrying capacity. To create steel joists in your model, see the following paragraphs.

    2. Click the point that you want to use, or type the distance from the start of the member to the desired point.

  3. Click the end point of the joist.

You can modify the joist position in both 2D and 3D views.

  1. Select the joist.
  2. Select the end node that you want to move.
    Note: Ensure that only the desired end node is highlighted in the Select Entity tooltip.
