随着密肋壁板结构的大量推广,对密肋壁板结构在服役阶段的安全可靠性进行综合评价,为结构的改建、扩建以及加固、维修提供依据,具有重要现实意义。基于模糊神经网络的结构安全可靠性评价方法的基本理论和评价过程,利用改进的模糊神经网络模型对密肋壁板结构进行安全可靠性评价。工程实例分析结果表明,利用该方法进行密肋壁板结构安全可靠性评价是合理、科学的。
With the extensive promotion of the structure of the multi-ribbed wall, the comprehensive evaluation on the safety and reliability of the multi-ribbed wall structure during the service period provides the basis for the reconstruction, expansion, reinforcement and repair of the structure, which has important practical significance. Based on the basic theory and evaluation process of structural safety and reliability evaluation of fuzzy neural network, the safety and reliability of multi-ribbed slab structure is evaluated by the improved fuzzy neural network model. The result of engineering example shows that it is reasonable and scientific to evaluate the safety and reliability of the multi-ribbed wall structure by this method.
