Triaxial compression tests on concrete were performed. The specimens of the triaxial compression tests were partially loaded in the axial direction, and the fracture strength of the concrete was investigated. The experimental results were compared with the results of an analytical method proposed by the authors. The process of the analysis was as follows: The shapes of fracture in these tests were reverse truncated cones. The stress on the cone was dicided by Griffith's fracture criterion. The cone was inserted into the specimen, and the fracture mechanism began when the stress in the circumferential direction on the outside cone reached the tensile strength of the materials. Experimental values generally agree with the analytical results. Therefore this study showes the strength of concrete is affected remarkably by Griffith's fracture criterion on the tensile strength of the materials.
