Question

Is it possible to consider the static zero position in a time history analysis?

Answer

Yes, it is possible to consider the static zero position in a time history analysis. For this, you can use the "Stationary state" function (not available in the linear modal analysis).


This function allows you to read a condition from a load case or a load combination that exists over the entire time history. These include the deformations, the stiffness modifications, and the states of nonlinearities.

This function can be activated in the RF‑/DYNAM Pro add-on module, in the "Calculation Parameters" tab of Dynamic Load Cases.


The time history diagram is well suited for results evaluation. In the attached example, Load Case 1 with the dead load was defined as a stationary state. In the time diagram, you can see that the deformations oscillate about the value that is reached by the static zero position.
