摘要：According to the basic properties of fluctuating wind, Simiu spectrum and linear autoregressive filter method, a program of Simiu spectrum-time curve has been compiled in the MATLAB. The time history of fluctuating wind velocity for a few points has been simulation based on Simiu spectrum. The results show that the method is feasible. Taking the FRP bracket-line coupling system as an example, the wind-induced vibration response of the structure at different angles of wind and wind speeds is analyzed by using the finite element software ANSYS. The results show that the wind in the 90 degree direction is the most unfavorable wind direction for the whole structure according to the three kinds of angle wind calculated at present and when the 0 degree wind acts on the structure, wires have a certain damping effect in the bracket-line coupling system. By comparing and analyzing the influence of different wind speeds and wind attack angles, it is found that in the bracket-line coupling system, the bracket structure is more sensitive to the increase of wind speed while the conductors are more sensitive to the change of wind attack angle.
