Wind and seismic both have mandatory load patterning that the user cannot disable.
Load Type | Description |
|---|---|
Wind | Splits the load combination into one with pressure, and one with suction. |
Seismic | Due to not knowing the direction of the acceleration from the seismic event, the seismic loads are all |
