Imperfection

This window contains parameters that are necessary for the determination of imperfection for given member sector. The fundamental parameter is the coordinate called "Sector beginning". This point is automatically considered as the end of previous sector and is used for the calculation of the sector length.

Imperfection parameters

Following parameters shall be specified for the imperfection determination:

Neglect imperfection

  • The consideration of the imperfection may be switched off with the help of this setting. Following parameters won't be enabled in that case.

Different sector length for buckling

  • If the fundamental length for the imperfection calculation differs from the sector length l, this check box should be switched on and the fundamental length should be defined in the input field "Length". In other cases, the sector length is considered as a fundamental length for the imperfection calculation. The sector length is updated automatically after any modification (e.g. insertion of new sector).

Length

  • The fundamental length l0 that is used for the calculation of the imperfection.
