how to equate response spectrum dynamic to static method in robot

[Anonymous]

good day sir , 

im looking for help how can we make an option in robot to equate response spectrum dynamic to static method

You may scale the base shear factor to match the value from the later.

TANK YOU SIR I MEANT THE RESPONSE WHEN USING CARVE , SEE THE ATTACHMENT PLEASE

I may be wrong but I don't think you can easily do so (I mean in general not in RSA itself).

THANK YOU IN ADVANCE , if we look to these attachments below ( this used by anther Software ) , have a look please .

My point is does Robot done the change or( scaling ) 0 automatically

yes it is. i can not see it in the robot , have a look to attachments

Any Explanation

Hello,

in your screen capture there was no Ag because this screen capture was made for IBC 2012 code. For this code final accelerations of the spectrum are calculated automatically from the parameters specific to this code:

Artur's screen capture was made for EC 8 code:

It also resulted in different analysis type.

As concerns extending the list of available codes for seismic analysis and for instance adding EC8 please see this video:

Great thanks for both of you for help and support . yes , i have done a small test model to know if we make sure that the robot will take the scaling of response automatically or not , what i got thats . the result of response are shown with no scaling , see the attachments please what can we do about this , any suggestion . Again thank you for your cooperation, regards

Spec carve, and Seismic were used

[Pawel.Pulak]

If you want to make some scaling or reduction for spectral analysis it can be done in analogous way as shown by Artur in this response.

It is possible by modification of Direction component for specific direction in parameters of the spectral case.

Artur used the factor of 2 but it is also possible to use factor lass than 1 to make reduction.

Good Day Yes . you are right , about RESPONSE IN ROBOT THE problem was in the response model definition , after define it we got what we waiting for
