CACULATION METHOD FOR PRESTRESSING LOSS OF BONDED CFRP TENDONS
-
摘要: 通过6根有粘结预应力CFRP筋混凝土梁的单调静力试验,结合系统查阅的国内外有关试验研究资料,对有粘结预应力CFRP筋混凝土梁中CFRP筋预应力损失的计算方法进行了研究,并提出了有关设计建议。Abstract: Six concrete beams prestressed with bonded CFRP tendons under static monotonous loadings are tested.Combined with relevant test results at home and abroad,the calculation methods on prestressing loss of bonded CFRP tendons are studied,and the corresponding design suggestions are proposed.
