Abstract: The equivalent static wind load model is used, which considers the randomness of average wind pressure and the random process of pulse wind pressure and the stochastic dynamic effect on structure. By introducing equivalent extreme-value event, the reliability of structure is simplified as series system of each failure mode and corresponding equivalent extreme variable quantity is proposed. Then, point estimate method is used to solve statistical moment of equivalent extreme variable quantity and according to the statistical moment information four order moment method is used to solve the system reliability index and system failure probability of the structure system. The research of 1000 kV UHV SZT2 transmission tower system shows that the moment method is simple and efficient, can spread to apply in the reliability analysis of practical projects.
