摘要
本文在分析试验获得的不同恒定温度下砼应力—应变曲线的基础上,通过假定,提出了映射温度流动路径,给出了具体的计算公式,并进行了试验验证。结果表明。
In this paper, the behaviors of stress strain curves of concrete were investigated at different temperatures. From the analysis of the test results, the method of determining temperature increment path, shining temperature flowing path, is presented and relative formulas are given. It is shown that the results of calculation by this method agree well with the test results.
