     in most cases concrete structures are modeled considering simplified behavior of elastic material. such a behavior, however, does not have capability to yield adequate answers right after crack initiation. in this paper the most accurate model for reinforced concrete structures so-called concrete damage plasticity is addressed. this model includes post cracking behavior of reinforced concrete structures in compression and tension as well as elastic and plastic stiffness degradation effects. since concrete damage plasticity encompasses all behaviors of concrete, it requires plethora of laboratory test data. parameters for which the model demands are also introduced along with required laboratory tests the parameters need to be determined. having known that concrete structures possessing damage behavior cannot be modeled by conventional solving procedures, explicit method is also proposed to illustrate this type of material behavior. finally yet importantly, one example of above-mentioned application showing the accuracy of the problem is successfully given.
