IDA analisis with loading factors

[eppy]

Hi,
why I have the same results of IDA changing loading factor?
thank you

Do you mean the IDA scaling factors? You should get different results for different values of the IDA scaling factors

[eppy]

Yes I mean scaling factor in IDA Parameter window. I said loading factor because they are also called in post processor window. If I insert two distinct scaling factors I have the same results in terms of displacement, rotations and reactions. How it is possible? What's probably wrong?
thank you

Two questions:
1) Are you applying the dynamic time-history loads?
2) Can you post the exact string of the IDA scaling parameters, so that I have a look

I loaded a time history curve and I added dinamic time history load in applied loading windows as the number of restreints at base of structure.
I used 1 5 and 10 as distinct scaling factors in IDA Parameters window.

Make sure that you select the different analyses with the different scaling factors from the corrsponding menu in the menu bar (initially it is set to 'Analysis No.1 - Scaling factor: 1'

In post processor window I select the menu you told about but I have the same results also refreshing page and changing analysis.

This behaviour seems very strange, since we have not faced similar problems in the past.
Please send the input file to 'support@seismosoft.com', so that we have a look at it.
