GGU-RETAIN: "Young's modulus/Specific weight"/"Specific weight" menu items

This menu item opens two different dialog boxes depending on whether you are working with a section list or with user-defined section data:

• "E modulus/Specific weight"
  When working with the section list, you must enter Young's modulus and specific weight of the wall. From the former the bending line is calculated, from the latter the self-weight of the wall.

• "Specific weight"
  Using user-defined section data Young's modulus is entered in the corresponding dialog box, so that here it is only necessary to specify the specific weight of the wall.
