To specify load cases and combinations

  1. Select Settings > Basic Load Cases The Basic Load Cases dialog opens.
  2. (Optional) If the Load Type selection is not already specified for each load case, select it from the drop-down list:
    LOAD 9: DEAD LOAD Dead Load
    LOAD 10: LIVE LOAD Live Load
  3. (Optional) If both loads are not already added to the Primary Load Cases list, click the [+] button when a load case is selected in the Analysis Load Cases list to add it.
    Note: You can import previously saved load cases and combinations to use by clicking the Import Load Cases & Combinations button and selecting an .ldsx file. Refer to the following steps on how to create a load settings file.
  4. Click OK. The Load Combinations dialog opens.
  5. Click Add From Analysis. The load combination from the analysis file is added for strength design checks.
