摘要
介绍了一种后张预应力连续梁的试验方法。在试验中，预应力次弯矩是通过调整支座高度来实现的。采用该试验方法建立起来的预应力连续梁与实际工程中的预应力连续梁是等价的。
A test method of post-tensioned prestressed concrete continuous beam is presented in this paper.In the test,the prestressed secondary moment is established by adjusting middle support height.The prestressed concrete continuous beam built by the method is equivalent to the beam in practice.
