受压钢筋对RC梁正截面承载力影响的理论分析

Theoretical Analysis of the Influence of Compression Reinforcement on the Bending Capacity of Doubly Reinforced RC Section

从理论上分析了受压钢筋对 Ｒ Ｃ 梁正截面承载力的影响规律，并提出了 Ｒ Ｃ梁的钢筋压拉比及正截面极限承载力等概念，可供设计者参考使用。

This paper theoretically analyses the influence of compression reinforcement on the bending capacity of doubly reinforced RC section.It puts forth such concepts as tension compression ratio and ultimate bending capacity etc.,to which reference can be made in design.
