CENTRE POINT OF DIAPHRAGM

Question:

WHERE TO SEE THE COORDINATE POINT FOR DIAPHRAGM ON EACH STORY? WHY WHEN CLICK THE ECCENTRICITY RATIO TO OBTAIN THE STIFFNESS CENTRE, ERROR SAYING CANNOT ADD OR REPLACE BUILDING DATA APPEAR? 

Answer:
Hello,

To see the coordinate point for diaphragm, please refer to the below image.


And for the error message, could you send me the relevant model and the screen shot of building control dialog of your model file?

Thank you.

Attached here with the error that i face for your further action and assistance.

Hello,

Could you send me the model file and the version information ?
Thank you.

Hello,

Please refer to the below online manual contents.

Story Stiffness Center

Select load cases, which will be applied to calculate the story stiffness center for calculating eccentricity ratios. Each of these load cases is assumed to be parallel with GCS X, Y axes. The stiffness is also calculated on the basis of load cases, which are not parallel with X, Y axes in which cases a warning message is generated.

X-Directional Load: Select a load case, which will be used to calculate the story stiffness center relative to Y-axis.

Y-Directional Load: Select a load case, which will be used to calculate the story stiffness center relative to X-axis.



In your model file, you select the same load case for the each story stiffness center. Therefore, create the load case which are parallel with X, and select it for the X-Directional Load Case. And create the load case which are parallel with Y, and select it for the Y-Directional Load Case like below image.

And then you can successfully define the Building Control.
Thank you.

Best regards,
