dEZignLink for STAAD.Pro
Constraints and Recommendations

  1. STAAD Windows: Using two STAAD windows simultaneously while operating this tool is not recommended.
  2. Login Restrictions: If the tool is logged into a new workstation, the session on the previous workstation will automatically be logged out.
  3. Column Selection: When using the SELECT tool to select columns, stub columns are not included. This tool doesn't consider stub as Main columns.
  4. Secondary Beam Identification: If a beam is supported by a column on one side and a beam on the other, the tool classifies it as a secondary beam.
  5. Releases: Columns, Bracings and Truss members are not assigned releases by this tool.
  6. Knee Bracing: Contributions of knee bracings in reducing effective lengths are not considered. This aligns with common industry practices.
  7. Rafter Bracings vs. Plan Bracings: Bracings in inclined roofs are categorized as Rafter bracings and are not included in the plan bracing category.
  8. Renumbering Limitations: STAAD has a renumbering limit of 999,999 members. If this tool exceeds this limit, the user must manually re-assign numbers.
  9. Floor Groups Validation: The tool includes all members at a level (except bracings) in Floor groups. Adjust as needed to ensure that floor groups contain the members making closed geometry.
  10. Effective Length for Unsegmented Members: Effective lengths (LY, LZ, LX, etc.) are not defined for members with no intermediate nodes, as STAAD defaults to the full member length.
  11. Effective Length Decisions:
    • Effective lengths (LY, LZ, LX, etc.) require Engineering judgment due to dependencies such as:
      • The strength of the lateral restraining members.
      • Linking of lateral restraining members with bracings.
      • Whether the lateral restraining members are removable.
    • This tool, by Default, assumes lateral restraining members which are modelled are sufficiently strong and braced too.
    • Modify Design Parameters whenever required as per actual project scenario.
  12. Vertical Bracing Contribution: The tool does not account for the support provided by vertical bracings connected to the middle of a beam above when calculating DJ1 and DJ2 parameters for that beam. This aligns with common industry practices.
  13. Design Parameter Adjustments:
    • Adjust design parameters manually for members with Beta angles other than 0°, 90°, 180° or 270°.
    • Modify design parameters for members supported by trusses, cantilever beams, cantilever columns as required.
    • Please note that this tool does not define design parameters for Rafters, Plan bracings, Vertical bracings or Truss members.
  14. General:
    • Many features of this tool are not designed to handle structures with Curved members or Plate elements.
    • The tool performs best with Regular and Orthogonal structures, delivering recommendable results in most cases.
    • Users are advised to thoroughly review the outputs generated by this tool.
    • The primary objective of this tool is to save substantial time by automating repetitive STAAD activities. Tasks that usually require hours can now be completed in seconds, allowing users to focus on more critical design aspects.

By understanding these limitations, users can better adapt their workflows and apply necessary manual adjustments wherever required.
