Results

After the successful calculation, the results of a modal analysis load case are displayed: You can see the first mode shape in the work window, the eigenvalues and natural frequencies of the individual mode shapes in the table. The results of the dynamic analysis are thus fully integrated into the program interface of RFEM or RSTAB.

01 Results of Modal Analysis in Work Window and Table

Work window

Select the mode shape whose results you want to graph from the list at the top of the ' Navigator - Results '. You can also use the and buttons to toggle between the individual mode shapes.

04 Select Mode Shape

The following result types are available for the graphic display in the Navigator:

• Eigenform : absolute total displacement, normalized displacement in u_X, u_Y or u_Z, normalized rotation in φ_X, φ_Y or φ_Z
• Masses : translational components of the displacements u_X, u_Y or u_Z, rotational components of the rotations φ_X, φ_Y or φ_Z
• Values on surfaces

Table

The result tables of the dynamic analysis are displayed automatically when you display the results of the dynamic load case. You can use the categories and subcategories to control the display of the results in the table (see chapter tables of the RFEM Manual). Various subcategories are available for modal analysis. They are presented in the following chapters.
