Concrete Damage Plasticity Model Parameters

[atakulaksizoglu]

Hi everyone. I am modelling a reinforced concrete H-joint on an FEA software. Obviously I need to provide Concrete Damage Plasticity parameters to model the inelastic behaviour of concrete. However, I am having hard time trying to find the CDP parameters for C90 concrete, which I have in the model. I was wondering if there is any 'plug-in-your-variables' constitutive relations to obtain the CDP parameters for various concrete strengths. To be more specific, I am talking about a simple formulation where I can put in my concrete strength and Elasticity Modulus etc.. to get the parameters I should put in the software. If not, I would appreciate if somebody would direct me to a source in which I can find CDP parameters for fck=90MPa concrete. Thank you.

I'm not handy about your request, but i hope this help you.

I am not familiar with CDP parameters, so help me understand....are you trying to figure out what parameters are necessary, the numerical values for the parameters, or both? Are these parameters unique to the software you are using?
