Story Mode Shape Table – MIDAS Support

Function

Check the mode shapes by stories in a spreadsheet format table.
When "Story Shear Force Ratio>Consider Story Module"is checked in the "Model/Building/Control Data", accurate shear forces can be obtained for the story having the overlapping Module.
When Modules are defined in Structure > Building > Story > Define Module button, the Module data is displayed in the first column of the table.
Table Tool in Gen NX offers a variety of powerful built-in functions. Refer to Usage of Table Tool for detail directions.

Call

From the Main Menu select [Results] tab > [Type : Analysis Result] > [Table] group > [Story Tables] > [Story Mode Shape Table]

Input

From the Records Activation Dialog, select the Modes for which story mode shapes will be checked.
Refer to Usage of Table Tool and check the following data:

When Modules are not defined

Story : Story ID

Level : Story Elevation

X : GCS X-coordinate of the story mass node (center of mass)

Y : GCS Y-coordinate of the story mass node (center of mass)

Mode : Vibration mode number

UX : Value of the mode shape in GCS X-direction

UY : Value of the mode shape in GCS Y-direction

UZ : Value of the mode shape in GCS Z-direction

RX : Value of the rotational mode shape about GCS X-axis

RY : Value of the rotational mode shape about GCS Y-axis

RZ : Value of the rotational mode shape about GCS Z-axis

When Modules are defined

The Module column is generated only when the Modules are defined. Mode shapes for each story are calculated as per the following.

Note
1. GL level (1F) is not generated.
2. The bottom floors of upper Modules are not generated.

Module : Module name is defined in Structure > Building > Story > Define Module button
