| 摘 要： | 冷拔钢丝预应力圆孔板是广泛使用的结构构件.但关于它的斜截面承载能力目前研究尚少,在规范中也尚无具体规定.本文在试验研究的基础上指出圆孔板斜截面破坏有两种类型,配置箍筋不能提高其受剪承载力,并给出了简单实用的斜截面承载力计算公式。

| Abstract: | The cold drawing wire prestressed concrete slab with circle hole is widely usedas a structure member.But up to now its indined section bearing capacity isstudied very little and there is no specific requirement in civil engineering code.Based on experiments the paper presents simple practical formulae for computing in-clined section bearing capacity and shows that the slab with circle hole has two col-lapse shapes and the stirrup can't enhance its shear bearing capactiy. |
