*BUCKLING LENGTH
Define buckling length data for buckling strut response of frame elements with PIPE sections.

This option is used to define two sets of coefficients used in the ISO equation that predicts for frame elements with buckling strut response. For a user-defined buckling envelope it can be used only in conjunction with both the *FRAME SECTION, SECTION=PIPE, YIELD STRESS= option and the *BUCKLING ENVELOPE option. For the default buckling envelope it can be used only in conjunction with the *FRAME SECTION, BUCKLING, SECTION=PIPE, YIELD STRESS= option, with or without the PINNED parameter.

Product: Abaqus/Standard

There are no parameters associated with this option.

Data line to define the buckling length coefficients: 

First (and only) data line:

  1. Effective length factor in the first cross-section direction.

  2. Effective length factor in the second cross-section direction.

  3. Added length in the first cross-section direction.

  4. Added length in the second cross-section direction.
