摘要：
The wind load plays an important role in structure dynamic analysis. Transmission towers collapse a lot because of the effect wind load, so the design of transmission towers must consider precisely the influence of actual wind load. On the basis of analyzing the characteristics of wind load, an elaborated AR (Auto-Regressive) model based on linear filter method was developed to simulate the velocity of turbulent wind load for the transmission tower structures. Use Simiu spectrum in which turbulence changing along with height of tower to simulate the turbulent wind load of 500KV cat-head transmission towers. The results show that the simulated spectrum and the objective spectrum of wind velocity agree well. The method provides useful references for anti-wind design of transmission tower structures.
