Abstract：Taking a 500kv high-voltage transmission tower in Shenyang as the prototype, they introduce aeroelastic modeling of high-voltage transmission towers,which meets the similarity theory for wind tunnel tests. It provides a feasible method for aeroelastic modeling. A formula for the pressure of rain loads is put forward. Through pressure scale ratio is equal to geometry scale ratio, they get a formula for scale ratio of wind-rain loads first in wind tunnel tests. In the actual wind tunnel tests, they suppose diameter of simulation for rain loads in the wind tunnel is equal to diameter of the actual rain loads. They get number density of simulation for rain loads in the wind tunnel is equal to the number density of the actual rain loads. This method is simple, and provides a theoretical basis for the wind-rain loads simulation in the wind tunnel tests.
