摘    要:首先对12根具有不同剪跨比、预应力度和箍筋及纵钢筋含量的无粘结部分预应力砼梁抗剪强度性能进行了试验研究。通过对影响梁抗剪强度的因素及斜截面破环形式的分析,提出计算抗剪强度的经验公式。

关 键 词:无粘结梁  部分预应力砼  抗剪强度  试验

Abstract:First, 12 unbonded PPC beams with various shear -span ratios,various prestressing degree and different reinforcement amounts of stirrup and longtitute steel bar have been tested to study the shear strength. By discussing the factors affecting the shear strength of unbonded PPC beams and the failure mode of inclinded section of the beams,an empiric formula for calculating the shear strength has been presented.
Keywords:unbonded beams partially prestressed concrete  shear strength. test
