Based on the formal solutions of the buckling eigen equation
the probability density evolution equation for the random buckling eigenvalue is derived considering the random wind loading.Taking the averaged wind speed at 10m height and roughness length as the random factors
the random buckling bearing capacity for a super-high cooling tower is then analyzed.Furthermore
both the mean and the standard deviations of the capacity are calculated.It is indicated that there exhibits a general shape for the probability density function of the random buckling capacity.And the mean of the random buckling bearing capacity is close to that one computed by the averaged parameter.However
the variation of the random buckling bearing capacity is between the corresponding values of averaged wind speed at 10m height and roughness length.
