| 摘 要： | 介绍了缓粘结预应力筋的构造和工作原理,通过3根缓粘结预应力混凝土梁的受弯试验研究了其开裂弯矩、极限弯矩、裂缝分布和荷载-挠度关系等缓粘结预应力混凝土梁的受力性能,并与有粘结和无粘结预应力理论计算结果进行了对比分析,得出缓粘结预应力混凝土梁的受弯规律,为缓粘结预应力混凝土梁的设计计算提供了参考。

| Abstract: | The structure and the working principle of the retard-bonded prestressing tendon were introduced.The cracking moments,ultimate moments,crack distribution and load-deflection graphs of retard-bonded post prestressed concrete beams were studied through the experiment of 3 beams.The experimental results were compared with the theoretical and experimental results of bonded and un-bonded prestressed concrete beams,by which the bending law of retard-bonded post prestressed concrete beam was obtained and can be referenced in the designing of retard-bonded post prestressed concrete beams. |
