Buckling
The buckling results are only returned when a buckling analysis is requested in the settings object. Otherwise the string "disabled" is returned.
| Result Key |
Type |
Description |
| buckling |
Object |
Contains the buckling results for the analysis. |
The buckling results object is structured as shown in the table below.
| Reaction Key |
Type |
Unit |
Description |
| message |
String |
- |
A status message for the buckling solution. |
| factor |
Number |
- |
The lowest buckling factor of the structure. A number less than 1 indicates buckling is occuring. |
| effective_lengths_y |
Object |
Length |
Effective Length in each member's local y-axis. |
| effective_lengths_z |
Object |
Length |
Effective Length in each member's local z-axis. |
| critical_loads |
Object |
Force |
The critical load of each member (i.e. the load that will induce buckling in the member). If the member is not in compression then a string "NC" will be returned meaning "No Compression". |
| max_translation_member |
Number |
- |
The ID of the member that has the maximum buckling translation. |
| max_rotation_member |
Number |
- |
The ID of the member that has the maximum buckling rotation. |
