在连续载荷下,因为磨损和压紧,该滑动面是光滑的,将导致粘结应力的进一步下降,类似于无节钢筋的情况。
Under continued loading the sliding surface is smoothed due to wear and compaction, which will result in a further decrease of the bond stress, similar to the case of plain bars.
同时还应用了环形无粘结预应力钢筋张拉技术。
The ring unbonded prestressed reinforcements tension technique was also used at the same time.
由于无粘结预应力混凝土构件中预应力钢筋与周围混凝土之间可以相对滑动,导致了构件受力和变形不同于有粘结预应力混凝土构件。
Because the reinforcing bar and surroundings concrete can have opposite slip in unbonded prestressed concrete, Lead to stress and deflection differing from bonded prestressed concrete structure.
