Abstract

The experimental data and the mathematical models obtained for the dependence of the yield strength of building steels on the test temperature at its negative values are analyzed. The well-known methods of calculating the temperature-induced hardening are shown to give a significant error. A mathematical model is proposed for the dependence of the yield strengths of low-carbon and low-alloy building steels on a negative climatic temperature.

负温度下建筑钢屈服强度增加的估计

摘要

分析了建筑钢材屈服强度与负值试验温度相关性的实验数据和数学模型。计算温度引起的硬化的众所周知的方法被证明会产生很大的误差。提出了低碳和低合金建筑钢的屈服强度对负气候温度的依赖性的数学模型。
