Abstract: In order to study the influence of various uncertain factors on the wind-resistant performance of transmission towers, an uncertainty analysis method for tower structures subjected to wind loads was presented. At first,random samples were generated based on the Latin hypercube sampling（LHS） technique and then used to establish uncertain finite element models（UFEMs） for transmission towers, on the basis, the static non-linear buckling analysis for all UFEMs subjected to wind loads was conducted. After that the fragility curves of the collapse basic wind speed and corresponding collapsed-tower tip displacement were fitted with the lognormal distribution. At last the influence of wind attack angle on the fragility curves and failure paths of tower body were discussed. The results indicates that the deterministic tower model overestimates the wind-resistant performance of transmission tower, and the wind attack angle has a great influence on fragility curves and failure paths.
