【Abstract】 The feasibility of applying neural networks to evaluation of the performance of high strength concrete columns reinforced with concrete filled steel tube in the core of section was investigated. A three layer back propagation network is trained using the earthquake resistant behavior experimental data of the columns to predict the ductility of the columns. The predicted results agree well with the test results. In the further analysis about the influence of various parameters on the ductility, the results show that it is significant to put concrete filled steel tube in the core of section for the high strength concrete columns in improving its earthquake resistant performance.更多还原
