| 摘 要： | 通过18根无腹筋部分预应力砼单筋梁的试验.研究了部分预应力砼受弯构件的延性,以及相对受压区高度和PPR对延性影响,并提出了一种计算延性系数的方法,该方法同样适用于计算普通钢筋砼和预应力砼构件。根据试验结果,建议部分预应力砼构件考虑地震作用时,其相对受压区高度不大于0.25。

| Abstract: | This article has studied the ductility of partial prestressed concrete flexure members and the effect of relative compression block depth as well as the PPR on the ductility by means of the tests of eighteen partial prestresssed concrete beams without compression steel and stirrups. A method to calculate the ductility factor is suggested, that is also suitable for reinforced concrete and prestressed concrete members. Based on the results of experiments, we suggest that the relative compression block depth should be below 0.25, when the earthquake acting is considered. |
