I am modeling a simply supported post tension slab subjected to impact load . The slab was modeled as a solid element whereas the tendons were represented as a linear elements (wires), knowing that tendons are not strait and have a profile (parabolic).
So I need to define the bond slip relation between wires (tendons) and solid part (concrete) to represent the real behavior. But I don't know how to do it and I found it somehow complicated?
any help please ..
thanks in advance
