Concept
In FEM-Design, vertical storey fundamental frequencies can be calculated regardless of material type.
Requirement
In order to run the Storey fundamental frequency calculations, following objects need to be defined in the model:
- Storeys (as the frequency is obtained at selected storeys)
- Mass (using the Mass or Load case – mass conversion)
Analysis
In Calculations dialog, select the Storey fundamental frequency, then in the right hand side dialog select the storeys that should be calculated.
Results
The results are stored under Storey fundamental frequency. Following type of results are available:
Vibration shapes (translational and rotational displacements): for bars and shells
Level masses
Results can also be listed in tabular form
