Abstract

Abstract: The formula for the estimation of shear strength of prestressed concrete beams proposed in reference[1]was discussed in this paper.A simpler and more rational formula was put forward for reference.

Key words: shear strength, shear span to depth ratio, steel ratio, the shear carried by concrete

摘要： 本文对文[1]提出的预应力砼简支梁斜截面抗剪强度公式进行了修正和简化,并给出了具有97.73%保证率的建议公式,供研究和设计参考。

关键词: 抗剪强度, 剪跨比, 配筋率, 砼抗剪力
