TR.45 Printing the Force Envelope
This command is used to calculate and print force/moment envelopes for frame members. This command is not available for finite elements.
General Format
PRINT { FORCE | MAXFORCE } ENVELOPE (NSECTION i) list-spec
list-spec = { LIST memb-list | (ALL) }
Description
Where:
| Parameter | Description |
|---|---|
| NSECTION i | the number of equally spaced sections to be considered in printing maximum and minimum force envelopes. i is an integer up to 96, though not recommended to be less than 12. If the NSECTION i command is omitted, i defaults to 12. |
MAXFORCE command produces maximum/minimum force values only of all sections, whereas the FORCE command prints maximum/minimum force values at every section as well as the max/min force values of all sections. The force components include FY, MZ, FZ, and MY. The SECTION command (as described in TR.40 Load Envelope) does not define the number of sections for force envelopes. For the sign convention of force values, refer to G.18 Member End Forces
