The invention relates to a lattice tower angle wind load distribution coefficient identifying method and a tower wind load determining method, belonging to the technical field of engineering. The lattice tower angle wind load distribution coefficient identifying method considers the influence of wind at different angles, which is more consistent with the actual results, and has better applicability and higher precision; in addition, by calculating the wind load of the tower when the wind with different angles is applied, the wind load of the transmission tower is obtained more accurately, andthe application scope is wider.
