With the default settings, the program displays the results of the envelope and the global directions X, Y, and Z that have a response spectrum assigned. These options are available at the top of the Navigator list (see the image Selecting Envelope or Direction ), so you can control the result display accordingly.
SRSS – Square Root of Sum of Squares
For a load case, the result designation specifies the type of envelope as follows:
| Description | Result Type |
|---|---|
| SRSS | Total envelope X, Y, Z |
| X | Envelope of all mode shapes in X |
| Y | Envelope of all mode shapes in Y |
| Z | Envelope of all mode shapes in Z |
| X, Mode Shape n | Envelope of the nth mode shape in X |
| Y, Mode Shape n | Envelope of the nth mode shape in Y |
| Z, Mode Shape n | Envelope of the nth mode shape in Z |
If you have specified in the Load Cases and Combinations dialog box that partial results for load cases or result combinations are to be output, these results are also available for selection for the load cases or the load cases used in the RC.
The result description comprises the load case number and the respective subresults. For Load Case 7 (LC7), for example, this is as follows:
| Description | Result Type |
|---|---|
| LC7.SRSS | Total envelope X, Y, Z |
| LC7.X | Envelope of all mode shapes in X |
| LC7.Y | Envelope of all mode shapes in Y |
| LC7.Z | Envelope of all mode shapes in Z |
| LC7.X, Mode Shape n | Envelope of the nth mode shape in X |
| LC7.Y, Mode Shape n | Envelope of the nth mode shape in Y |
| LC7.Z, Mode Shape n | Envelope of the nth mode shape in Z |
Scaled Sum (100% / 30% or 100% / 40%)
For a load case, the result designation specifies the type of envelope as follows:
| Description | Result Type |
|---|---|
| Scaled Sums | Total Envelope |
| X 100% ❘ Y 30% ❘ Z 30% | Factorized envelope of all mode shapes in X (100%), Y (30%), and Z (30%) |
| X 30% ❘ Y 100% ❘ Z 30% | Factorized envelope of all mode shapes in X (30%), Y (100%), and Z (30%) |
| X | Envelope of all mode shapes in X (100%) |
| Y | Envelope of all mode shapes in Y (100%) |
| Z | Envelope of all mode shapes in Z (100%) |
| X, Mode Shape n | Envelope of the nth mode shape in X |
| Y, Mode Shape n | Envelope of the nth mode shape in Y |
| Z, Mode Shape n | Envelope of the nth mode shape in Z |
For a result combination, the result description comprises the load case number and the respective subresults. For Load Case 7 (LC7), for example, this is as follows:
| Description | Result Type |
|---|---|
| LC7.Scaled Sums | Total envelope |
| LC7.SSX | Factorized envelope of all mode shapes in X (100%), Y (30%), and Z (30%) |
| LC7.SSY | Factorized envelope of all mode shapes in X (30%), Y (100%), and Z (30%) |
| LC7.SSZ | Factorized envelope of all mode shapes in X (30%), Y (30%), and Z (100%) |
| LC7.X | Envelope of all mode shapes in X (100%) |
| LC7.Y | Envelope of all mode shapes in Y (100%) |
| LC7.Z | Envelope of all mode shapes in Z (100%) |
| LC7.X, Mode Shape n | Envelope of the nth mode shape in X |
| LC7.Y, Mode Shape n | Envelope of the nth mode shape in Y |
| LC7.Z, Mode Shape n | Envelope of the nth mode shape in Z |
Absolute Sum
For a load case, the result designation specifies the type of envelope as follows:
| Description | Result Type |
|---|---|
| Absolute Sum | Total envelope X, Y, Z |
| X | Envelope of all mode shapes in X |
| Y | Envelope of all mode shapes in Y |
| Z | Envelope of all mode shapes in Z |
| X, Mode Shape n | Envelope of the nth mode shape in X |
| Y, Mode Shape n | Envelope of the nth mode shape in Y |
| Z, Mode Shape n | Envelope of the nth mode shape in Z |
For a result combination, the result description comprises the load case number and the respective subresults. For Load Case 7 (LC7), for example, this is as follows:
| Description | Result Type |
|---|---|
| LC7.AS | Total envelope |
| LC7.X | Envelope of all mode shapes in X |
| LC7.Y | Envelope of all mode shapes in Y |
| LC7.Z | Envelope of all mode shapes in Z |
| LC7.X, Mode Shape n | Envelope of the nth mode shape in X |
| LC7.Y, Mode Shape n | Envelope of the nth mode shape in Y |
| LC7.Z, Mode Shape n | Envelope of the nth mode shape in Z |
