M. To assign member imperfection for members
To assign member drift or camber for use with an imperfection analysis, use the following procedure.
- (オプション) Select the members which will all have the same member specification assigned.
-
On the
Specification ribbon tab, select the
tool in the
Specification group.
The Member Specification dialog opens to the Imperfection tab. - Do either of the following:
- Select the Local Direction of the imperfection and then type the Value, which is taken as a ratio of the member length to offset (i.e., L/d).
- (オプション)
For Camber, type a
Respect value which is used to determine when
to skip camber imperfection calculations.
This ratio results in the camber imperfection
calculations being skipped when:
- the compressive load is small,
- the member stiffness (EI) is large, or
- the member is short
-
Either:
To… Do the following… add the specification to the model and assign to the current member selection click Assign. add the specification to the model for later assignment click Add.
