Subresults

With the default settings, the results of the envelope as well as the global directions X, Y and Z are output to which you have assigned a response spectrum . These options are available at the top of the Navigator list (see also image # extbookmark manual|image036780|Select envelope or direction #) so that you can control the display of results accordingly.

If you have activated the option Save results of all selected shapes in the Spectral Analysis Settings and have assigned this setting to a load case, the results of all selected mode shapes (see chapter Selection of Shapes ) for the directions X, Y and Z, to which a response spectrum was assigned.

In the load case, the individual results of the spectral analysis are saved and available as partial results (envelopes). They replace the export of load cases and result combinations, as was necessary in the add-on module RF-/DYNAM Pro of the program generation RFEM 5/RSTAB 8.

The available partial results depend on which of the spectral analysis settings you have assigned to the load case and for which excitation directions you have specified a response spectrum . The various options are shown in the following tables.

SRSS - Sum of Square Roots Rule

In the case of a load case , the result description names the type of envelope as follows:

Description Result type
SRSS Total envelope X, Y, Z
X Envelope of all eigenmodes in X
Y Envelope of all eigenmodes in Y
Z Envelope of all eigenmodes in Z
X, mode n Envelope of the nth eigenmode in X
Y, mode n Envelope of the nth eigenmode in Y
Z, mode shape n Envelope of the nth eigenmode in Z

If you have specified in the 'Load Cases and Combinations' dialog box that partial results are output (see picture # extbookmark manual|image030496|Activate partial results for result combinations #), these results are also available for the load cases used in the RC.

The result description is made up of the load case number and the respective partial results. For load case 7 (LC7), for example, this is as follows:

Description Result type
LF7.SRSS Total envelope X, Y, Z
LF7.X Envelope of all eigenmodes in X
LF7.Y Envelope of all eigenmodes in Y
LF7.Z Envelope of all eigenmodes in Z
LC7.X , mode shape acc Envelope of the nth eigenmode in X
LF7.Y , mode shape acc Envelope of the nth eigenmode in Y
LF7.Z , mode shape acc Envelope of the nth eigenmode in Z

Scaled sum (100%/30% or 100%/40%)

In the case of a load case , the result description names the type of envelope as follows:

Description Result type
Scaled sums Total envelope
X 100% ❘ Y 30% ❘ Z 30% Factored envelope of all eigenmodes in X (100%), Y (30%) and Z (30%)
X 30% ❘ Y 100% ❘ Z 30% Factorized envelope of all eigenmodes in X (30%), Y (100%) and Z (30%)
X Envelope of all eigenmodes in X (100%)
Y Envelope of all eigenmodes in Y (100%)
Z Envelope of all eigenmodes in Z (100%)
X, mode n Envelope of the nth eigenmode in X
Y, mode n Envelope of the nth eigenmode in Y
Z, mode shape n Envelope of the nth eigenmode in Z

In the case of a result combination, the result description is made up of the load case number and the respective partial results. For load case 7 (LC7), for example, this is as follows:

Description Result type
LF7.Scaled sums Total envelope
LF7.SSX Factored envelope of all eigenmodes in X (100%), Y (30%) and Z (30%)
LF7.SSY Factorized envelope of all eigenmodes in X (30%), Y (100%) and Z (30%)
LF7.SSZ Factorized envelope of all eigenmodes in X (30%), Y (30%) and Z (100%)
LF7.X Envelope of all eigenmodes in X (100%)
LF7.Y Envelope of all eigenmodes in Y (100%)
LF7.Z Envelope of all eigenmodes in Z (100%)
LC7.X , mode shape acc Envelope of the nth eigenmode in X
LF7.Y , mode shape acc Envelope of the nth eigenmode in Y
LF7.Z , mode shape acc Envelope of the nth eigenmode in Z

Absolute sum

In the case of a load case , the result description names the type of envelope as follows:

Description Result type
Absolute sum Total envelope X, Y, Z
X Envelope of all eigenmodes in X
Y Envelope of all eigenmodes in Y
Z Envelope of all eigenmodes in Z
X, mode n Envelope of the nth eigenmode in X
Y, mode n Envelope of the nth eigenmode in Y
Z, mode shape n Envelope of the nth eigenmode in Z

In the case of a result combination, the result description is made up of the load case number and the respective partial results. For load case 7 (LC7), for example, this is as follows:

Description Result type
LF7.AS Total envelope
LF7.X Envelope of all eigenmodes in X
LF7.Y Envelope of all eigenmodes in Y
LF7.Z Envelope of all eigenmodes in Z
LC7.X , mode shape acc Envelope of the nth eigenmode in X
LF7.Y , mode shape acc Envelope of the nth eigenmode in Y
LF7.Z , mode shape acc Envelope of the nth eigenmode in Z
