The Graitec PowerPack on top of Autodesk Advance Steel, allows you to create beams with openings from catalogues or defined by the user. It is worth noting that beams with openings are considered to be already fabricated.
Beams with openings are used as structural members, with the main advantage being that the beam depth and strength are increased without adding additional material. A beam with openings is produced by cutting a beam lengthwise following a rectangular pattern. The top and bottom halves are then staggered and welded together to create a deeper, stronger beam.
When creating a beam with openings from a catalogue, only the sections from the specific catalogues are available in the dialog window.
When creating a user-defined beam with openings with web openings, the values for the Height, Width, Flange and Web thickness of the "I" section can be modified as desired.
A new beam with opening sections can be added in the database using the Save as option from the Catalog Manager. After the section dimensions are added, use the Save option to store them in the database.
