含裂缝钢纤维混凝土破坏分析的一种新方法

A NEW ANALYTICAL METHOD FOR FAILURE ANALYSIS OF STEEL FIBER CONCRETE WITH A CRACK

  • 摘要: 采用有限子层剪滞模型,并结合线弹性断裂力学,研究了带裂缝钢纤维混凝土试样的拉伸破坏问题,求得了与实验结果较吻合的拉伸破坏强度,证实了该分析方法的正确性和可靠性,可为钢纤维混凝土的破坏分析提供一种新的研究途径。

     

    Abstract: The tensile failure of steel fiber concrete with a crack is studied utilizing the shear-lag model of finite sub-layers in conjunction with the linear elastic fracture mechanics. The tensile failure strength is found to be in good agreement with the experimental results. Thus, the correctness and reliability of the present analytical method is verified.
