hi SeismoStruct Team
plz help me, how to model passive, semi active and active fluid viscous damper(diagonal brace) in seismostructure software???
thanks

Re: fluid viscous dampers
Hi again
I want to model the steel moment frame with concentrically brace fluid viscous damper.
How i can define the real nonlinear fluid viscous damper for concentrically brace?

Re: fluid viscous dampers
As discussed in the Help System (Element Classes -> Damping Element):
"dampers are normally modelled by means of link elements with adequate response curves that may be able to characterise the non-velocity-dependent (at least within the typical range of earthquake velocities) force-displacement relationship of a given damper"
Producers of damping devices provide the response curves of such devices under typical velocity ranges (i.e. values of velocity that one normally observes during an earthquake), exactly so that one may then model the effect of such dampers through the use of a link element.
