摘要
钢绞线因其高强度、低松弛的特点被广泛运用。本文通过具体事例，对后张法预应力钢绞线伸长值的计算与分析做了阐述，并借助具体公式推算和总结出了伸长值的阙值，希望对行业发展有所帮助。
Steel strand is widely used because of the characteristics of high strength, low relaxation, Through specific examples, this article expounds calculation and analysis of elongation value of post-tensioned prestressed steel strand, and then calculates and sums up the threshold of the elongation with the help of specific formula, which is hoping a better industry development.
