Live load patterning checks 5 different conditions for flexure, and 2 conditions for torsion. If any of these conditions result in the same loads as a previous condition it is not checked. Any point moments added the member will be included in all patterns. The live load patterns are as follows:

Horizontal Members

1. All live loads are applied to the member

2. All loads whose magnitude is pointing down.

3. All loads whose magnitude is pointing up.

4. Alternates loads between spans to be down - up - down - up and so on.

5. Alternates loads between spans to be up - down - up - down and so on.

6. All loads that create positive torsion, or no torsion.

7. All loads that create negative torsion, or no torsion.

1. All live loads are applied to the member

2. All loads with a positive eccentricity.

3. All loads with a negative eccentricity.

4. Alternates loads between spans based on eccentricities to be + - + - + and so on.

5. Alternates loads between spans based on eccentricities to be - + - + - and so on.
