This example has illustrated the use of a buckling shape as imperfection. Depending on the geometry<br />
of the structure, this imperfection can have a large influence on the results due to the additional<br />
moments which occur.<br />
When using this method, it is very important to double check all applied steps: small changes to the<br />
loading or geometry require a re-calculation of the buckling shape and amplitude before a non-linear<br />
analysis may be carried out.<br />
As a final note: the buckling shape only gives information about a specific zone of the structure. The<br />
imperfection is applied at that zone and results/checks are only significant for that zone. Other<br />
combinations of loads will lead to another buckling shape thus to each load combination a specific<br />
buckling shape must be assigned and a steel code check should only be used on those members on<br />
which the imperfection applies. Since the applied buckling shape corresponds to a global mode, failure<br />
of these members will lead to a collapse of the structure.
