| Abstract: | By means of summarizing internal and external documents and comparing experimental results, the calculating formula of stress and strength factor for concrete finite boy having ellipse fixed fissure in advance is revised. The axial elongation test results of test samples having different fixed fissures in advance are compared and analyzed. The revised coefficient of concrete test samples having rectangle fixed fissure simplified to ellipse fixed fissure is calculated. |
