摘要
推导出通过测量先张法预应力筋放松后的回缩来计算预应力筋的传递长度公式,阐述了后张法分批超张拉批间影响和调整次数等问题。
The paper presents a formula of calculating the transmission length of the tendon by measuring the retraction of the tendon after release. The influence between batches and the adjustment times etc. of surplus pre-stressing in batches are set forth here.
