对PPC受弯构件的界限的相对受压区高度ξ_b和ξ_(pb)的讨论

The Discussion about Bounding Relative Height of Compression Zone ζb and ζpb of PPC Beams

分析了PPC受弯构件在达到承载能力极限状态时,预应力钢筋和非预应力钢筋的应变,推导了界限的相对受压区高度ξb和ξpn的公式,并对它们进行了讨论.

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, the fomulaes about bounding relative height of compression zone b and pb.are deauced and discussed.
