为了研究60年基准期下的可变荷载取值标准,采用了60年基准期下的荷载超越概率与现行规范50年基准期下荷载超越概率一致的原则,对建筑结构60年基准期的可变荷载标准进行了具体研究,最终给出楼面活荷载、风荷载和雪荷载的相应结论。该项目的研究方法可以推广到不同设计基准期下可变荷载的标准取值。
In this paper, the equal exceedingprobabilityprinciple is carried out to determine the characteristic value,statistical parameters of variable load. The equal exceeding probability principle is based on the equal exceeding probability between 50-year design reference and 60-year design reference. The corresponding results of floor live load, wind load and snow load are given. This study can also be applied to the structure of different design reference period.
