| Abstract: | A geometric analysis method of structural reliability calculation was proposed based on BP urtificial neural network and response surface method.A durability evaluation of the concrete corroded by the seawater was also conducted by the reliability index obtained.The data experiments showed the model of nueral network by this method can imitate the true ultimate state function,and it had a prospect of wide use in the question of the durability evaluation of concrete. |
