Hi Silvia and Frank,
I am thinking about removing fiber at a specified time step of dynamic analysis. For example, I want to remove a steel fiber in RC column after strain 0.12 to representing rupture. If removing the fiver is available, I dont need to spend a long time on development of a constitutive model to satisfy this requirement.

It is always good to make OpenSees more flexible since flexibility is its important advantage. I am sure capacity of removing fiber will benefit other researchers for different purposes.

Thank you.

Yuhao

Hi, Yuhao

You can use the MinMax material in opensees shown in the following link:

good luck!

Dear Silvia
what's your idea about this script that writte in attache file? is that corroct?
i use it from this article:
1- Ramadan, T., and Ghobarah, A. (١٩٩٥), “Analytical model for shear-link behavior”. ASCE J. of Struct.
Eng ١٢١:١١, ١٥٧٤-١٥٨٠
2-Prinz, G.S.(٢٠١٠), “Using Buckling-Restrained Braces in Eccentric Configurations” Ph.D. dissertation,
Dept. of Structural Engineering, Univ. of Brigham Young

attache file is: http://www.mediafire.com/view/?3q1n3extf1zy2qb

thank you

I think it would be useful to have commands that allow the user to modify elements after the elements were defined. For instance be able to replace the nodes that were used to define a specific element, or the geometric transformation of an element.
