Abstract: The quick and efficient simulation of wind speed profiles is a necessary condition for performing time history response analysis of bridges. This paper introduces the harmonic synthesis method for simulating wind fields and applies it to simulate the random wind field at the location of the Hanjia River Yangtze River Bridge on the Yuli Railway. The paper also provides a detailed comparison of the effects of different aerodynamic admittance functions on the fluctuating wind speed spectrum. The explicit Cholesky decomposition of the wind speed spectrum density matrix is performed, and the simulation efficiency is greatly improved by using FFT techniques. A wind field simulation program is developed, and the correctness of the program is verified by comparing the wind speed spectrum and correlation functions, laying a solid foundation for the effective analysis of wind-induced vibrations in structures.
