Article Preview

Abstract:

In this paper, the three-graded random aggregate model of concrete beam is established by using the Monte Carlo method. And in order to close to the engineering practice, the initial imperfection is putted in to this model. Then the impact load is applied to the beam, and the numerical calculation is carried out, the results of numerical simulation and experiments of previous are compared. It is found that the damage process of concrete and calculation results are similar to the experimental results of previous. Thus proof that the model is suitable to the engineering practice.
