在役结构可靠度的拟对数正态分布法及其应用

摘要

According to the realities of existing engineering structures,the logostic normal distribution is used to described the common variables in the analysis of structural reliability.The checking point method of simulation logistic normal distribution is proposed.The appliation of the logistic normal distribution is demonstrated by the reliability analysis of durability for corrosion of steel reinforcement.%根据在役工程结构的实际情况，采用对数正态分布来描述可靠度分析中常遇到的随机变量；讨论了拟对正态分布的验算点法；通过对钢筋混凝土钢筋锈蚀的耐久性可靠度分析，说明了拟对数正态分布法的应用。
