Web Openings
Steel beams can have openings modeled in the web. The size and the location of the opening must be specified, but then the program can optimize the beam and the stiffener plates (when required). To model an opening:
- Select the Typical level type.
- Select .
- For the Location, set the Horiz distance to 4 (1.25).
- Set the Position in Web to Centered
- Set the Shape and Size to Rectangular
- Make the opening 10 (250) high by 12 wide (300).
- Click [Add].
- With the target cursor, select each one of the steel beams in the bay from E to F, 2 to 3.
- Pick the west end of those beams to place the opening relative to that end.
- Repeat for the rest of the beams indicated below.
Web openings which occur near the end of the beam or within a small distance of a supported beam will always generate a warning in the design. For more information on web openings, refer to the Steel Beam module on-line documentation.
