CFRP-PCPs复合筋预应力损失分析及其计算

Analysis and calculation of prestressing loss of CFRP-PCPs composite bars

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 prestressing loss in the current concrete structures design code, study of the prestressing loss of CFRP- PCPs composite bars is conducted by testing and calculating, and an applicable algorithm is presented. Then we measure the prestressing loss of CFRP-PCPs composite bars of ten CFRP-PCPs embedded reinforcement concrete beams. The experimental results agree with the proposed algorithm.
