A structure modification allows you to individually adjust stiffnesses of materials, objects, and object types.
Modify Stiffnesses
In the Structure Modification dialog box, select the object types for which you want to adjust the stiffnesses. Thus, new tabs become visible where you can change the parameters. It is possible to change the properties of materials, cross-sections, members, surfaces, hinges, and supports. Furthermore, stiffnesses can be modified for some design add-ons.
Deactivate Nonlinearities
If objects with nonlinear properties are used in the model, you can deactivate the effect of individual object types. This way, you can prevent, for example, failing "Member Types" like tension and compression members or lifting forces in the case of a nonlinearly acting "Surface Support". All selected objects are applied as linearly acting in the calculation.
Other Options
The "Deactivate objects" function allows you not to apply certain model objects in the calculation. For example, you can analyze the effect of temporary members (jack posts) or supports without deleting the members or supports.
