Abstract—Behavior of structure subjected to blast and impact loads has to be analyzed with considering the effect of high strain rate. Material behavior will be changed under the condition that loads are applied to structures during a short period of time, which must be taken into account. In this paper, the nonlinear behavior of RC beams subjected to blast loads is analyzed by means of the layered-section approach. Using the proposed numerical method, the tendencies of numerical analysis are figured out with the number of element and time interval. Finally, correlation studies between analytical and experimental results are carried out in order to testify the validity of proposed numerical method. Then, it has been found that the numerical results show very good agreement with the experimental result.
