| Abstract: | Simulation method for the impulse wind load is presented by using auto-regressive(AR) model in the time domain.Based on the power spectral density function of impulse wind load,the time history of impulse wind load varying along with the space positions has been concisely simulated.The results of a case study indicate that the method presented here is reasonable,feasible,and consistent with the spectrum accurately. |
