This paper uses the commercial code of ADINA to analyze the vortex shedding for two staggered circular cylinders and changes in the wind load placed on the cylinders along with changes to the approach wind velocity and the incidence angles of wind. On this basis, this paper has reached the following conclusions: First, the Karman vortex takes place predominantly when the Reynolds number is 4,970, while the narrow turbulent wake prevails in the rear of the cylinders when the number stands at 331,344. This air current phenomenon as well as approach wind incidence angle results in the asymmetry of pneumonic force against the downwind cylinders. Second, the upwind and downwind cylinders discharge vortexes with almost identical frequencies under the simulated conditions of this paper, but the differences in phase between vortexes in the two cylinders do change by approach wind velocity.
