摘要 针对二跨连续梁的特点 ,对两跨对称抛物线布筋的无粘结部分预应力混凝土连续梁进行了单跨集中加载试验 ,并与两跨对称集中加载的试验进行了对比 ,共计做了 4根连续梁的试验 ,研究了布筋方式和荷载形式对无粘结预应力梁受弯性能的影响。 This test includes two span continuous prestressed concrete beams with tendons of parabolic profile under single span loading or two span symmetric loading.The results of test beams of the bend behavior and the ultimate increment of unbonded tendon with parabolic profile under this type of loading are discussed.
