根据现行的混凝土结构设计规范中预应力损失的基本原理,通过实验与计算结合的方法对CFRP-PCPs复合筋的预应力损失进行研究,并提出一种适用的算法.通过对10根CFRP-PCPs内嵌加固混凝土梁的CFRP-PCPs复合筋预应力损失的测量,结合相应算法,结果显示吻合良好.
According to the basic principle of prestress loss in the design code of concrete structure, the prestress loss of CFRP-PCPs composite bars is studied through the combination of experiment and calculation, and a suitable algorithm is proposed.Through the analysis of ten CFRP-PCPs The measurement of prestress loss of CFRP-PCPs composite bars embedded with reinforced concrete beams, combined with the corresponding algorithm, the results show good agreement.
