The results show that the percentage of transient loss of prestress is not much relation to the stretching stress, that the measured results don ' t agree well with the calculated results to some extent, based on the actual Code for Design ; and that the losses due to anchorage deformation and retractation of tendons account for a large percentage of the total loss.

试验结果表明：瞬时损失的百分数与张拉应力的大小关系不密切；实测预应力损失值与按现行规范中确定预应力损失的方法计算结果有一定差异；锚具变形和预应力钢筋内缩在总损失中所占比重较大。
