FORECASTING THE COMPRESSION-RESISTING OF SQUARE SECTION-CONCRETE COLUMN BY BP NEURAL NETWORK
-
摘要: 通过收集大量试验资料,建立了基于BP神经网络预测碳纤维加强复合材料(CFRP)加固混凝土方柱抗压性能的网络结构模型,通过网络模拟预测值与真实试验值的比较,证明了该网络模型能够有效地预测加固后的混凝土方柱抗压性能,并对影响加固效果的各个因素进行了初步分析,其结论符合研究报道。Abstract: Through collecting a lot of test information,a BP neural network is set up, whi ch can forecast the compression-resisting of square section-concrete columns r einforced with CFRP. By comparing the simulation data with those of the experime nt, it is proved that the network can forecast efficiently; and the factors infl uencing the reinforcing effect are also analysed and the conclusions are in acco rd with the research report.
