The wind load is an important role in structure of dynamic loads. Transmission tower be often broken down with effect of the wind load, the design must consider the wind load precisely the influence. This article elaborated the wind basic characteristic foundation and inferred the linear filter method to simulate transmission tower structure turbulent wind load theory, and used the turbulence along the Simiu spectrum, which changed with high, to the 500KV cat-head straight line tower to carry on the turbulent wind simulation. The computed result indicated that the simulated spectrum and the goal spectrum agreed well, the structure for the actual wind project to provide reference.
