【Abstract】 According to the dynamic characteristics, the statistic response parameters of the tall building (high rise building) resisting wind loading were obtained based on the codes and modal decomposed method. The structural dynamic reliability under a gusty wind was acquired through the theory of the extreme values and the normal distribution method. The occurring frequency of the wind loading was assumed to obey the Poisson distribution, then the method to calculate the dynamic reliability of structures resisting the wind loading in the reference period was obtained. This method is easy to use.更多还原
