GGU-RETAIN: "Verifications/Partial factors" menu item

If you are analysing with the partial safety factor concept, you will see a dialog box for defining the partial factors (here: Soldier pile wall selected).

The partial factor for the permanent action because of water pressure can be reduced according to EAU 2012 under certain boundary conditions. The same applies to the passive earth pressure partial factor used for calculating the design moment.

In the dialog box you can deactivate verifications that you do not want to carry out. If you have selected "Soldier pile wall" or "Bored soldier PW" as the retaining wall, a further area appears for verifying the sum H:

In the "Default values" group box you can use the "To DIN 1054:2010" button to transfer the partial safety factors for the various load cases of DIN 1054:2010 or EC 7. The selected design situation is automatically entered at the top of the dialog box and can, if desired, be displayed in the General legend. However, you can also use your own designations here.

In the partial safety concept according to EC 7, the designations of the load cases have been changed:

• Load Case 1 is now DS-P: Persistent Design Situation

• Load Case 2 is now DS-T: Transient Design Situation

• Load Case 3 is now DS-A: Accidental Design Situation

In addition, there is a seismic design situation: DS-E. In the DS-E design situation all partial factors = 1,0.

It is also possible to select the partial safety factors compliant with Austrian standards using the "To ÖNORM EN 1997-1" button.
