PPC梁中钢筋的搭配及屈服条件

The schemes and the yielding conditions of steel reinforcement in PPC beams

本文分析了 PPC受弯构件在达到承载能力极限状态下 ,在不同的钢筋级别搭配下 ,预应力钢筋和非预应力钢筋所产生的应变和应力 ,并给出了两者都达到其抗拉强度设计值所需的条件。

In this paper, the strain and stress of prestresed reinforcement and common reinforcement are analyzed when PPC beams are in the states of ultimate bearing capacity and various groups of steel reinforcements are used。 The conditions to yield strength of prestressed and commen reinforcements are given too
