Partial factors

The "Partial factors" dialog window serves to enter the analysis partial factors. Individual combo lists allow for choosing a design approach and the way of inputting these coefficients.

The choice in the "Input of partial factors" combo list determines the way of inputting the analysis partial factors.

For default setting the window offers values of partial factors recommended by Eurocode 1997-1. The "Design approach" combo list allows for selecting one of the three "Design approaches". Based on the selected design approach, the bottom part of the dialog window displays partial factors on action, material or resistance, respectively, and combination factors for variable actions. In such a case the values of partial factors cannot be modified. A partial factor adjusting the action of water is an exception. 

The user setting allows for specifying arbitrary values of partial factors. Default values, according to national annexes, can be copied into the user values by pressing the "Take over values" button.

Furthermore, it is also possible to choose individual EU countries – the window then displays partial factors corresponding to the selected national annexes (NA). In most cases, only one Design approach is then allowed based on NAD and the program (the type of the analyzed geotechnical task).

The program allows for inputting each set of parameters four times – for individual design situations (persistent, transient, accidental and seismic). The program then adopts coefficients based on the design situation set in the frame "Settings".
