摘要
以3片16m足尺无粘结部分预应力混凝土梁为试验对象,对其极限承载能力进行了测试,在试验的基础上,对现有的无粘结部分预应力混凝土梁中无粘结力筋的应力增量公式进行了探讨。
In this paper,through the experiments of 3 pieces of 16M unbonded partially prestressed concrete beams, the bending strength of them is investigated. Based on the experiments,the formulas for the ultimate stress increment in unbonded tendons are studied.
