Load Cases
The time history analysis is based on a load case which has the analysis type Time history analysis | Accelerogram or Time History Analysis | time diagram.
You can use several load cases of the type 'Time History Analysis' for the model.
Loads
Loads represent the loading due to a specific action. They can act individually on nodes, linearly on members, or distributed on surfaces.
In the time history analysis with time diagrams, the loads defined in a load case of the type 'Time History Analysis | time diagram' with the selected time diagram. In this case, the static loads define the size, direction, and position of the excitation.
