The "Stage settings" frame serves to input settings valid for a given construction stage.
The selected design situation determines the safety coefficients to be used in the analysis of a given construction stage.
The frame view depends on the selected verification methodology.
Next, the frame serves to specify the pressure type acting on a wall based on the allowable wall deformation. Providing the wall is free to move, the active pressure is assumed, otherwise, the pressure at rest is used. The third option enables to load the wall by increased active pressure.
The reduction of soil/soil friction angle can be considered in one of following ways:
- do not reduce
- reduce to 2/3φ (AASHTO)
- reduce to 0
- input reduction coefficient
The wall stem is loaded either by pressure at rest or by the same pressure as that acting on the entire wall.
