| 摘 要： | 针对斜剪破坏和剪切粘结破坏两种破坏模式,研究了型钢轻骨料混凝土梁抗剪承载力。考虑型钢和混凝土界面存在的粘结力,推导了剪切粘结破坏抗剪承载力计算公式。结合型钢混凝土结构技术规程中型钢普通混凝土梁斜截面抗剪承载力计算公式,提出了型钢轻骨料混凝土梁抗剪承载力预测模型。试验结果比较和验证表明,该预测模型不仅具有足够的精度,而且也适用于型钢普通混凝土梁。

| Abstract: | Shear capacity of steel reinforced lightweight concrete beams is investigated for the two failure types of diagonal shear failure and shear bond failure. Shear bond capacity formula is deduced considering the existing bond force between the encased steel and concrete interface. Shear capacity predict model of steel reinforced lightweight concrete beams is proposed combining with shear capacity equation of steel reinforced normal concrete in technical specification for steel reinforced concrete composite str... |
