结构钢强度变异的统计分析

Statistical Analysis for Strength Variance of Structural Steel

本文对钢结构最常用A_3钢材的屈服强度,收集了大量实测数据。运用概率统计知识进行了统计分析,得出A_3各组钢材屈服强度的分布规律及参数。可进一步加深理解许用应力的含义和概率可靠性设计应用、参考。

For yielding strength of A_3 steel, statistical analysis is carried out tased en a great mass of experimental data. Distribution mcdels and parametcrs of yiolding strength of caoh group of A_3 stecl is determined. It is helpful for deeper undorstanding to allowable stress and would be applied to statistical reliability design.
