文章介绍了单梁进行体外无粘结预应力筋加固试验,计算了体外预应力加固的正截面抗弯承载能力,分析评价了体外预应力加固桥梁的正截面承载能力和静力刚度的加固效果。
In this paper, the single beam is used to test the unbonded prestressed tendons in vitro. The flexural capacity of normal section under external prestressing reinforcement is calculated, and the reinforcement effect of the normal section carrying capacity and static stiffness of externally prestressed reinforced bridges is analyzed and evaluated .
