通过用短暂时距内的平均预期最大值代替瞬时预期最大值的方法来得到风速峰值和阵风风速系数，并讨论了地表粗糙度、基本风速、桥面高度和时距对阵风风速系数的影响程度，最后给出了阵风风速系数的数值．
The peak wind speed and gust wind speed coefficient were obtained by replacing the instantaneous expected maximum value with the average expected maximum within a short time span. The effects of surface roughness, basic wind speed, deck height and time span on the wind-gusting wind speed coefficient were discussed Finally, the gust wind speed coefficient is given.
