Modelling approach to catch the global response

Post by MereenBaloch »

Hey everyone!
I'm currently working on modelling a cantilever column to perform some time history analysis. I'm interested in the force displacement hysteresis behaviour of my model, and I want it to follow a predefined uniaxial material model globally.
I cannot simply use a fibre section and assign the material model because material model is based on a stress strain law and the global force displacement response may not exhibit the same behaviour because in this way the global response will be an aggregated response of the different fibre materials. I am looking for an approach by which my all structure should behave as my assigned material model.
Any comment is highly appreciated.
Regards
Mereen
