GGU-RETAIN: "Sections" menu item
Upon selecting "Sheet pile wall" and "Using section list" you see a dialog box which appears almost exactly the same as that for soldier piles. Here, too, the "Steel design to EC 3" check box must be activated. The sheet pile wall sections can be stored in a ".spw_ggu" file.
If you do not design to EC 3, it is important to note that for sheet pile wall sections the area "A" must be entered in [cm²/m] and the moment of inertia "I" in [cm4/m]. Also note that the section values given in the table assume that a shear resistant connection exists between the supplied double sections. The variable S is the first moment of area of the section and s is the web thickness. The "alp" variable is the opening angle of the section. The value of "S·sin(alp)/s" is required for verification of shear stress.
If "Combined sheet pile wall" is selected, the sections dialog box is expanded slightly:

You can have new sections generated by the program using the "Generate tubular section" button. The new sections created here can be saved in a ".kom_ggu" file.
