Answer:
In RFEM 5 and RSTAB 8, there is the option to assign various stiffnesses to the individual objects, such as nodal supports, by load case. This function can be found in the calculation parameters of load cases and load combinations.
In RFEM 5, the individual objects can also be deactivated by load case.
The tab allows you to ignore certain objects of the model in the calculation. This way, the effect of temporary members (construction supports) or supports can be analyzed, for example.
To consider the adjustments in the calculation, it is necessary to activate the Modify Stiffness function in the Calculation Parameters of the program.
