Re: Fluid Viscous Dampers internal force

You have two or more nodes on the same coordinates that are connected to different elements. These elements are not connected to each other.

Re: Fluid Viscous Dampers internal force

We checked again the small model that you have sent. It seems that there is a problem with the connection of the elements, the model cannot even run eigenvalue analysis. Check again the conectivity of the elements, this is probably the reason why the model does not converge.

Re: Generic Hysteretic Model - hyst_mat - background document

You can find the description of the input parameters of the curve in the corresponding Annex of the User's Manual, form which you will probably you will get a good understanding of the curve. Other than that, you can better understand the role of each parameter, by changing them in the Materials mod...

Re: Kent-Scott-Park (confined fibers response issue)

Hello Felippe and thanks for the model, It seems that you are right, the confinement factors are not considered in the con_ksp model in v2021. We were checking things with v2022, which is still under development and where the bug has been already fixed (the bug will appear fixed, when v2022 will be ...

Re: Convergence problem in nonlinear dynamic analysis

The analysis with the smaller tolerance should provide better results. However, the big difference between the max. interstorey drift (close to zero vs. 0.05) is not reasonable for such a change in the tolerance of the convergence criterion. Make sure that your model is correct (e.g. run eigenvalue ...

Re: Fluid Viscous Dampers internal force

The model that you sent is huge wih more than 1600 elements, and we cannot obviously check things. Note that you have defined element damping, which might be the reason for the discrepancies that you get. If this is not the case, please send us a more simplified model that reproduces the problem, so...

Re: Fluid Viscous Dampers internal force

This is not reasobable, because with a force-based criterion with 0.001 kN tolerance, the differences should be very small.
Can it be that you are comparing local against global forces, or forces at different axes?
Can you please check things again?

Re: Initial stress/strain for steel material

No unfortunately, this is not possible. If you are trying to model prestressing, unfortunately this cannot be modelled directly by the program.

Re: Kent-Scott-Park (confined fibers response issue)

Can you send one of your models to support@seismosoft.com, so that we check things?
Thanks.

Re: Fluid Viscous Dampers internal force

If the elements are connected in series, this is not reasonable.
Can you please employ a more stringent convergence criterion and (if posible) a force based convergence criterion?
