Re: Fluid Viscous Dampers internal force

I also changed the global damping to none and the issue still exist.

Re: Fluid Viscous Dampers internal force

Thanks for your reply. I double checked my model. The problem was the links representing the foundations, the link elements were not defined in the element connectivity module. Although, the model runs now (attached). However, the  issue still exists. I have done a lot of trials, and I found that as...

Re: Fluid Viscous Dampers internal force

Hi As you suggested, I have checked without global damping but this issue still exist. The top of chevron braces is not supposed to be connected to the beam and it is intentional. The difference between dampers load and corresponding connected frame elements is still significant I sent you the simpl...

Re: Fluid Viscous Dampers internal force

I emailed my model to support@seismosoft.com.
the force in dampers are different than UC's connected to their ends (horizontal members)
it is obvious from early part of the record.

Thanks

Re: Fluid Viscous Dampers internal force

I am comparing internal force of a link element (damper) of F1 DOF and axial force of the connected frame element (elastic) F(A) DOF.
I can send you my model. Or the elements internal actions history.

Thanks

Re: Fluid Viscous Dampers internal force

Thanks for your response,
I did changed the convergence criterion to force based with 0.001 tolerance
but the problem still exist. I appreciate your instruction

Thanks

Fluid Viscous Dampers internal force

Hi I am using a link element with vsc_dmp in F1 direction and default lin_sym (with default values) for other DOFs, I have connected two elastic steel members (UC350) to the two ends of the damper, at top of a chevron brace. Although the link element is in series with elfrm element (UC350) the inter...

Infill interaction with column

Hi I understand that the masonry infill panels are simulated via 3 structs in each direction (2 for diagonal actions and 1 for shear). One end of the diagonal struts are connected to the corner of panel while the other ends are connected to the columns near the corner (eccentrically) That is to simu...
