Hi all!
I want to model hysteretic yielding steel damperapplied to the chevron configuration in the braced a frame. This damper can be modeled as bilinier model. I read from manual this damper can be modeled using link element through 2 node with zero length (coincide node). I am a little bit confused because this steel damper actually has certain length , let say 30 cm. Please guide me how to use link element with certain length

regards
daniel

Daniel, hi.

Typically, in such cases you do not necessarily model the damping device in explicit fashion, but rather through a phenomenological model, i.e. a zero-length link element that features a hysteretic behaviour similar to that exhibited by the damper in question.

You would the connect such link element to an elastic frame elementn, for instance, that would feature the physical length of your damper, so as to achieve the necessary structural connectivity.

If you search this Forum for the word "damper" you are likely to obtain further hints&tips. And if you google an expression such as "modelling hysteretic steel dampers" you also will surely find more guidance.
