GGU-RETAIN: "Special preferences" group box (Analyse)

In the "Special preferences" group box of the start dialog box of the "System/Analyse" menu item you can specify whether any area loads should be included in an earth pressure redistribution. You may "Redistribute ep to toe" and not, as is usual, to the load transition point.

Retaining walls subject to buckling hazards can be analysed using "2nd order theory". A system pre-curvature, which can be adopted at 1/150, must be defined for buckling analysis to DIN EN 1993-5 or DIN EN 1993-1-1. The direction of pre-curvature must also be defined (to the ground side or the atmosphere side). Whether a pre-curvature towards the ground side or the atmosphere side provides the more unfavourable design values is system-dependent: it is therefore absolutely vital that both directions are investigated in a buckling analysis (see "Theoretical principles: 2nd order theory").
