摘要
体系可靠度已经成为可靠度研究的重点,由于其功能函数大都为隐式功能函数,响应面法已成为计算可靠指标的主要方法,响应面法主要分为迭代序列响应面、混合响应面、神经网络响应面、模糊神经网络响应面,就最近几年响应面法的理论发展和工程运用作一总结。
The reliability analysis of complex large-scale structures is hindered by the implicit nature of the limit-state function.Approximation methods,such as the response surface method(RSM) are widely used to alleviate the computational burden of engineering analyses.There are many improvements on the response surface method when it is taken account on engineering analyses,such as sequence response surface method(SRSM),mixed response surface method(MRSM),artificial neural network(ANN),fuzzy neural network(FNN).It is summarised the theoretical development,the main characters and its uses in engineering analysis.
