WIND DISASTER VULNERABILITY ANALYSIS OF THE TRANSMISSION TOWER BASED ON PROBABILITY RELIABILITY

In this paper，a wind disaster vulnerability analysis of a cat-head-shaped transmission tower based on probability reliability was presented． The diagrams of the wind disaster vulnerability of the transmission tower in different damage state were drawn． Based on the analysis of the wind disaster vulnerability of the transmission tower in two direction，it is clear that the structural response and the structural bearing capacity follow a log normal distribution． And the tower can easily be damaged by the strong wind．
