摘要
提出了基于神经网络与响应面法相结合的结构可靠度计算的几何分析方法 ,通过得出的可靠指标对受海水侵蚀混凝土进行了耐久性评价。数值试验表明 ,该方法建立的神经网络模型可以很好地拟合真实的极限状态函数 。
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.
