结构的设计使用年限与结构重要性系数

On Structural Design Working Life and the Importance Factor of Structure

根据极值I型概率分布的性质 ,本文以楼面活荷载标准值在设计基准期内的超越概率为基准 ,计算了在不同设计使用年限楼面活荷载分布上具有相同超越概率的荷载值 。

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. [
