| Abstract: | The paper investigates the feasibility of using neural networks to analyze the seismic behavior of abnormal joints of reinforced concrete frame. According to the mechanism of feed forward Neural Network, Neural Networks technology is applied to built the complex non-linear relationship between the anti-shear capacities of the reinforced concrete abnormal joints under low reversed cyclic loading and the main factors. Back Propagation (BP)Neural Networks model is built to predict the strength of the reinforced concrete abnormal joints. According to the test data, satisfactory results are achieved. Therefore, it is proven that the neurocomputing is a practical and promising tool for the analysis on seismic behavior and mechanical properties of abnormal joints of reinforced concrete frame. |
