| Column Header | Data Type | Example / enum definition | Required | Description |
|---|---|---|---|---|
| Result on | Enum | On edge | yes | Specify where the result is, only option is 'on edge'. Prepared for future expansion (on opening edge..) |
| 2D member | String | B1 | yes | Reference to the name of 2D member in StructuralSurfaceMember |
| Edge | Integer | 2 | yes | The index starting with 1. The order is according to order of “edges” property in StructuralSurfaceMember |
| Result for | Enum | Load case Load combination |
yes | Specifies from where the result is coming from (from Load Case, Load Combination) |
| Load case | String | LC1 | yes, if Result for = Load case | Reference to the name of StructuralLoadCase |
| Load combination | String | COM1 | yes, if Result for = Combination | Reference to the name of StructuralLoadCombination |
| Combination key | String | 1.35*LC1+1.5*LC2+1.5*LC3+1.5*LC4 | no | Allows to define exact combination per result section Structure of string: ”LoadFactor1*LoadCase1+LoadFactor2*LoadCase2 +LoadFactorN*LoadCaseN” For envelopes and national standard (code) combinations, this column specifies for which exact combination the result is computed |
| Section at [m] | Double | 0.100 | yes | X coordinate on the edge(distance from the start node) where the result is located |
| Index | Integer | 1 | yes | Index of the section on edge |
| mx [kNm/m] | Double | 3.00 | yes | Result value of bending moment mx |
| my [kNm/m] | Double | 3.00 | yes | Result value of bending moment my |
| mxy [kNm/m] | Double | 3.00 | yes | Result value of torsion moment mxy |
| vx [kN/m] | Double | 3.00 | yes | Result value of shear force vx |
| vy [kN/m] | Double | 3.00 | yes | Result value of shear force vy |
| nx [kN/m] | Double | 3.00 | yes | Result value of membrane force nx |
| ny [kN/m] | Double | 3.00 | yes | Result value of membrane force ny |
| nxy [kN/m] | Double | 3.00 | yes | Result value of shear force nxy |
This attribute defines an order of the section on the edge, starting with 1 and increasing from the start to the end of the edge. This property helps to specify if the internal force is on the "left" or on the right side of the section.
See example on a beam below:
See index 6 and 7. One section, two values for normal (N) force. \
Section with lower index (6) identifies value on the left (closer to the origin of X-axis of the beam).\
Section with a higher index (7) identifies value on the right (further from the origin of X-axis of the beam).
