Rusted concrete column bearing capacity prediction method based on AdaBoost
The invention discloses a rusted concrete column bearing capacity prediction method based on AdaBoost. The method comprises the following steps: 1, firstly, collecting a large amount of test data of rusted concrete columns, including basic information and maximum bearing capacities of the concrete columns; 2, constructing dimensionless input variables based on the basic information of the concrete columns, and forming a training data set by taking the maximum bearing capacities as output variables; 3, putting the data set into an AdaBoost algorithm for training, and initializing an AdaBoost model; 4, introducing m weak learners to carry out iterative training, and adjusting a weight of each weak learner until an overall strong learner has optimal prediction precision; and 5, predicting the maximum bearing capacity of the rusted concrete column based on the trained AdaBoost model. The method is beneficial to prediction of bearing capacities of concrete structures considering the corrosion degradation effect.
