CBF buckling bracing

[senior]

one of the best ways to model bracing in opensees in URIZ and MAHIN model
( you can find it in this link : http://peer.berkeley.edu/publications/p ... ZMahin.pdf)

now my question is :
can i model "X bracing" with this model in opensees ? how ?

i think that you can use the basic principals proposed in that report to model X braces. just make sure to define the connection between two braces properly.

it needs an initial camber which is obvious how to model in the chevron braces. but in X brace because of connection between two braces, it is not as easy as that. do you know how to model this camber in X braces?

any answers?
