title = "Research on optimization method of reasonable arch axis of arch bridge based on Fourier series expansion",
abstract = "In this paper, an iterative optimization method for determining the ideal arch axis of arch bridge based on Fourier series expansion is proposed. In this method, the arch rib is discretized into multiple elements. By establishing the difference function between the initial arch axis and the ideal arch axis, introducing Fourier series expansion and boundary conditions, and taking the minimum bending energy as the optimization objective, the calculation formula of the ideal arch axis is constructed. Then the method is applied to the arch axis optimization of the actual bridge. The results show that the bending moment of the optimized arch axis under load is obviously reduced, thus improving the stability and safety of the bridge. This research provides broader options for arch axis selection and serves as a valuable reference for arch axis optimization methods in arch bridge design.",
