The behavior of the reinforced concrete materials under high strain rated loads significantly differs from their behavior under common loads. Therefore, more parameters such as strain variation rate, materials nonlinear modulus of elasticity, and under dynamic loads concrete failure rate, are required to model such behavior. In this paper, it is attempted to find out an appropriate model of concrete behavior in different resistive levels under high strain rated loads, applying the mentioned elements in concrete resistance. The proposed model is compared with the results of the experimentations and the results are finally evaluated. The results well show the desirable operation accuracy of the proposed model.
