| Abstract: | There are some errors between the established finite element initial model and the actual structure, which cannot accurately reflect the actual working status of the bridge. The author established a finite element model of a steel-concrete composite beam suspension bridge, based on the response obtained from the bridge load test, established its response surface model for optimization calculation, and modified the finite element model. |
