预应力筋的预应力对抗剪承载力有贡献作用,国内外规范中也明确了预应力筋的竖向分力的抗剪贡献,但对预应力筋的水平分力对抗剪的有利作用则鲜有研究.文章通过对预应力混凝土T梁的理论分析,提出了预应力筋水平分力对抗剪的有利作用的建议公式,并对如何确定该作用大小进行了试验设计研究.

The prestressing force of prestressed reinforcement will be contributing to shear capacity that is an explicit in the domestic and foreign standards,but the beneficial effect of prestressed tend on shear of horizontal component is little studied. Based on the analysis of prestressed concrete T-beam theory, the proposed formula on the shear action of horizontal component of the prestressed reinforcement is put forward, and it studies the experi...
