混凝土拉、剪临界破坏及纯剪强度

THE CRITICAL TENSILE-SHEAR FAILURE AND SHEAR STRENGTH OF CONCRETE

    摘要
  • 摘要: 本文基于混凝土微裂缝工作机理,提出了拉、剪临界破坏的概念,从理论上推导出了临界破坏的应力状态,并由此确定了混凝土的纯剪强度指标。利用该结果分析了Mörsch纯剪试验结果,符合程度良好。

     

    Abstract: In the present paper, the critial tensile-shear failure state of plain concrete is proposed, and failure criteria both for shear and tension failure are suggested. An expression for shear strength is derived. By using the method presented in this paper, a shear experimental results are examined, and a good agreement is obtained.
