Structure Modification:
Using a structure modification, you can individually adjust and modify stiffnesses of materials, objects, and object types afterwards.
Modify Stiffnesses:
In the Structure Modification dialog box, select the object types for which you want to adjust the stiffnesses.
After selecting the check boxes, you can see new tabs 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 there are the objects with nonlinear properties used in the model, you can deactivate the effect of the individual object types. In this way, you can prevent, for example, the failing "Member Types," such as 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.
