TO DO:

The pattern live-load factor (Pllf) is intended to account for variability in the live-load arrangement on a structure. Since live-load pattern is not automated, Pllf approximates its design effect.
...
Pattern live-load factors may be assigned to individual elements using the Design > Steel Frame Design or Concrete Frame Design > View/Revise Preferences command, as shown in Figure 1:
Figure 1 - Pattern live-load factor
Example
The maximum positive midspan design moment induced by uniform dead- and live-load application would be calculated as follows:
...
- Mpos MAX - maximum positive midspan design moment assuming a simply-supported condition with no continuity for live load
Given point loading, Mpos MAX would be calculated similarly as for uniform loading, in which a simply supported condition is assumed and the live-load factors specified are applied.
