Abstract:
The mixed model of improved exponential and power function and unequal interval gray GM(1, 1)model have poor accuracy in predicting the maximum pull-out load of anchor bolts. An optimal combination model was derived using the optimally weighted combination theory and the minimum sum of logarithmic squared errors as the objective function. Two typical anchor bolt pull-out engineering cases were selected to compare the performance of the proposed model with those of existing ones. Results showed that the optimal combination model was suitable not only for the slow P-s curve but also for the steep P-s curve. Its accuracy and stable reliability, as well as its prediction capability classification, were better than those of the other prediction models. Therefore, the optimal combination model is an effective processing method for predicting the maximum pull-out load of anchor bolts according to measured data.
