| Matrix or Vector | Midside Nodes [1] | Shape Functions | Integration Points | 
|---|---|---|---|
| All | With midside nodes | w = C1 + C2x + C3x2  | 2 | 
| Without midside nodes | w = C1 + C2x  | 2 | 
| Load Type | Distribution | 
|---|---|
| All Loads | Same as shape functions | 
The logic is similar to that given for SURF152 - 3-D Thermal Surface Effect.
