| 摘 要： | 根据极值Ｉ型概率分布的性质，本文以楼面活荷标准值在设计基准期内的超越概率为基准，计算了不同设计使用年限楼面活荷载分布上具有相同的超载概率的荷载值，讨论了其与结构重要性系数的关系。

| Abstract: | According to the properties of extreme value type I probability distribution, the load values on the different distributions of variable load, which have the same probability of exceedance, were calculated in the paper, while the probability of exceedance of the characteristic value of variable load within the design reference period was taken as reference datum. Besides, the relation between the calculated values and the importance factor of structure is also discussed. |
