Function
- Check the story inertia forces and story shear forces from the response spectrum analysis results 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 Shear(Response Spectrum Analysis) Table]
Input
From the Records Activation Dialog, select the Spectrum Load Cases for which story shear forces will be checked.
Refer to Usage of Table Tool and check the following data:
When Modules are not defined
Story Shear (for R.S)
Story : Story ID
Level : Story Elevation
Spectrum : Response spectrum load case
Inertia Force : Story inertia force
Shear Force : Story shear force
Spring Reaction : Reaction of a spring entered as a boundary condition (linear spring support)
Without Spring : Story shear force less the spring reaction
With Spring : Story shear force including the spring reaction
Note
The story inertia force is calculated from the member forces of the relevant story.
Eccentricity : Eccentricity from the mass center
Story Force : Shear force at each story level
Note
Shear Force represents the sum of shear forces of all the upper stories as well as the corresponding story, and Story Force represents the shear force acting on the corresponding story.
Eccentric Moment : Story Shear * Eccentricity
Note
These items are produced only when we apply 'Consider Accidental Eccentricity' in Load > Response Spectrum Analysis Data > Response Spectrum Load Cases.
Story Shear Force Coefficient
Story : Story ID
Spectrum : Response spectrum load case
Shear Force : Story shear force
Weight Sum : Total weight
Story Shear Force Co : Story shear force coefficient
Note
Produce the Story Shear Force Coefficient of (Roof level - 1) by dividing the story shear force of (Roof level-1) by the total weight of Roof level. The Story Shear Force Coefficient for roof level is ruled out. Base shear of a building structure divided by total weight will be the Story Shear Force Coefficient of bottom floor (1F).
When Modules are defined

Inertia Force : Story inertia force

Without Spring : Story shear force less the spring reaction
With Spring : Story shear force including the spring reaction

Eccentric Moment : Story Shear * Eccentricity

Story Shear Force Coefficient
Story : Story ID
Spectrum : Response spectrum load case
Shear Force : Story shear force
Weight Sum : Total weight
Story Shear Force Co : Story shear force coefficient
Note
Produce the Story Shear Force Coefficient of (Roof level - 1) by dividing the story shear force of (Roof level-1) by the total weight of Roof level. The Story Shear Force Coefficient for roof level is ruled out. Base shear of a building structure divided by total weight will be the Story Shear Force Coefficient of bottom floor (1F).
