Notional loads may be included in automatically generated load combinations. For example, an AISC Direct Analysis Method application is done through the following process:
- In the design preference, set design code to AISC360-05 / IBC2006.
- Select the Define > Load Combinations > Add Default Design Combos option.
- Select the Steel Frame Design option (Figure 1), then select Set Load Combination Data to specify the load cases used in generating load combinations. Include the specified load cases in both the strength and deflection load combinations by using the Code-Generated user Load Combinations for Steel Frame Design form (Figure 2). To include all loads, select All from the scroll-down menu, and then Copy to for each limit state.
