Power transmission tower line system wind load nonlinear finite element analysis method

The invention provides a power transmission tower line system wind load nonlinear finite element analysis method, and relates to the field of power transmission tower line system wind load nonlinearity. The invention discloses a power transmission tower line system wind load nonlinear finite element analysis method. The method comprises the steps of 1, wind direction angle nonlinear analysis; 2, performing finite element analysis on a power transmission tower line system under a wind direction angle; step 3, comparing and analyzing nonlinear results of the wind attack angle; and 4, further comparing and analyzing the nonlinear result of the wind attack angle. 0 degree, 45 degrees, 60 degrees, 90 degrees, 120 degrees, 150 degrees and 180 degrees are analyzed and compared, the situation that the 90-degree wind attack angle belongs to the dangerous working condition can be more intuitively obtained through different data and analysis results, and further analysis is performed through comparison of iron tower str
