Hi
I am working on maintenance of bridge columns. In my study I am using FRP on circular columns to enhance the strength and ductility. I used confined concrete 01 material and frp confined concrete available in opensees for simulating frp behavior. I try to compare the results from experiments and numerical, but these two results are not matching. I need your help to do this. I have one more question about confined concrete 01 material, my question is what value I should provide for confined concrete ultimate strain in confined concrete 01 model.
Thanks
Sai
