Abstract

Abstract: Based on the test results of 50 bonded P.P.C beams and 25 unbonded P.P.C beams, the comparison of shearstrength and behavior of unbonded P.P.C beams with bonded P.P.C beams is made.It is shown that unbonded P.P.Cbeams have lower ultimate shear strength.

Key words: bond, unbond, shear strength, comparison

摘要： 本文根据50片有粘结部分预应力砼梁和25片无粘结部分预应力败梁的剪切试验结果，对有粘结梁和无粘结梁的抗剪强度以及抗剪机理进行了比较．试验表明，无粘结梁的斜截面抗剪强度低于有粘结梁的斜截面抗剪强度．本文分析了导致这种现象的原因．
