| 中文摘要: |
| 基于缓粘结预应力混凝土两跨连续梁的受弯试验研究,对加载过程中预应力筋的摩阻力进行了分析研究,并计算了缓粘结预应力连续梁的预应力损失。通过分析得出了在预应力损失中孔道摩擦损失起主要作用的结论;对比试验中摩阻力测试值和预应力损失计算值,虽然二者存在一定的差异,但相差并不大,表明试验数据有一定的可信度,为在设计缓粘结预应力混凝土连续受弯构件提供参考数据。 |
| 英文摘要: |
| On the basis of the bending experimental on retard-bonded prestressed concrete two-span continuous beams,we analyzed the stretching friction in the process of loading and calculated the prestress loss of retard-bonded prestressed concrete.The experiment and analysis show two conclusions,one is that the loss of canal friction is the most important function in prestress loss;the other is that the stretching friction is almost the same as the calculation to prestress loss when consider the effects of friction in the design of retard-bonded prestressed concrete continuous beams. |
