摘要
现在的工程结构设计都已采用以概率理论为基础的极限状态设计法 ,但计算中的参数多为随机变量 ,因此要选择某一概率分布函数来描述随机变量的特征。主要介绍概率分布模式选择的不同对计算的可靠性指标所产生的影响。
Probability-based limit condition is adopted in the present engineering structural design, but the parameters for computation are mostly random variables. Therefore a certain probability distribute function is needed to describe random variables. The influence of the selection of probability distribute on the reliability of computation is mainly discussed.
