Abstract:A model is presented to forecast the terminal bearing capacity in the sections of reinforced concrete (RC) columns under bi-axial bending and compression. By taking the main factors affecting the bearing capacity, such as the section dimension, the concrete strength, the loading angle and the reinforce ratio, as the model parameters, and by using the numerical simulation results as the training specimens, a forecasting model is established based on BP neural network. It is verified that the proposed model is of excellent forecasting ability for the terminal bearing capacity of RC columns under bi-axial bending and compression.
Keywords:reinforced concrete  bi-axial bending and compression  bearing capacity  forecasting  neural network
