摘要
对预应力钢绞线选用不同的初始应力,得到不同的松弛率,从而找出初始应力与松弛率的关系。该关系显示在标准要求的检验范围内,松弛率对初始应力敏感,因此检验要尽可能减小初始应力的误差,确保松弛率的准确性。
To select different initiative stress can get different relaxation rate of prestressed steel strand and find out the relation between initiative stress and relaxation rate.The relation shows that the relaxation rate is sensitive to the initiative stress in the range of inspection required by standard,thus the inspecting should decrease the error of initiative stress if possible so as to assure the accuracy of the relaxation rate.
