受压区配筋量对矩形截面梁抗弯强度的影响

Theoretical analysis of the influence of quantity of reinforcement in compressed area on the bending strength of doubly reinforced beam of rectangle section

从理论上分析了受压区配筋量对双筋矩形截面梁抗弯强度的影响规律,并提出了双筋矩形截面梁的钢筋压拉比及极限抗弯强度等概念,可供设计者参考使用。

This paper theoretically analyses the influence regularity of compressed area on the bending strength of doubly reinforced rectangle section beam. It puts concepts of tension-compression ratio and ultimate bending strength of beam etc., to which reference can be made indesign.
