Description

Due to this structural design, a lateral and torsional restraint cannot be assumed here when determining the ideal elastic critical moment during the stability analysis. This reduces the structural resistance and therefore has to be considered. On the other hand, the ultimate load increasing capacity effect of the rotational restraint from the trapezoidal sheeting is taken into account.
