Modelisation of non linear dampers

[Anonymous]

Hi everyone,

I would like to know if RSA 2017 is able to model non linear damper that we need to design at each end of a long bridge.
Then we would use a time-history analysis to calculate the dynamic response of the structure (with sismic acceleration).

The relation between force and velocity would be as below :

F = C.V^a

F : force
C : damping factor
a : damping exposant (different than 1 ! probably equal to 0.10)
V : velocity
            
It seems that only linear dampers are possible right now (then a = 1)

Please tell me if there is way to do that.

If not, I would like to know if another Autodesk software is able to do so.

Thanks a lot for your help             

Regards

Unfortunately as for now only linear viscous dampers are available in Robot (c*v^alpha with alpha = 1)

The request to implement non-linear viscous dampers (alpha different than 1) is registered since some time - I have added your reference to it.
