Firstly, the simulation and validation method for typhoon field is proposed, in which the simulation is based on the non-stationary wind speed simulation method and the validation is fulfilled by introducing the nonuniform modulation evolution spectrum. Secondly, the typhoon load treatment method is established by means of the treatment method for normal wind. APDL language is used to develop the ANSYS into a time domain wind-vehicle analysis system. Finally, the response of a cable-stayed bridge is analyzed by the developed analysis system. The results show that the simulated power spectrum agrees well with the validated evolution spectrum, and that the simulation and validation method is rational and effective. It is also shown that the time history curves of bridge response under typhoon and the simulated typhoon wind speed have the same trend as the time-varying mean wind speed, and the fluctuation amplitude decreases with the decrease of the mean wind speed. The classical wind spectrum based on stationary characteristics is not suitable for typhoon simulation., authors=LIU Huanju, WU Jun, HAN Hexiang, XU Pengfei, DING Binyuan, authorsList=LIU Huanju, WU
