| Description | Taking the single-beam load test of the Laohe Bridge as the engineering background, a single-beam finite element model is established, and an improved response surface method is introduced to modify the single-beam finite element model. The central composite test design method and analysis of variance are used to screen for high significance Parameters, the response surface model is established instead of the single-beam finite element model to calculate the response value, and the model is modified based on the test data. The results show that the deviations between the calculated values and the measured values of the model after the correction have decreased from 15.3%, 12.7%, 14.4% to 2.34%, 2.01%, and 1.56% at L/4, L/2, and L3/4. The revised model meets the engineering accuracy requirements. The application of this method is of great significance for improving the accuracy of finite element models and identifying structural damage during the use of bridge structures.
