Triaxial and biaxial compressive strength of experimental specimens are understood by tensile strength of the concrete, with formation of a reverse truncated wedges which is built up symmetrically with a vertical line in the specimen. The reverse truncated wedges are formed by the shearing stress and nomal stress of "Griffith's fracture criterion". But the assumption of formation of the reverse truncated wedges has certain limitations for applying to structures such as the reinforced concrete structure. In this paper, an idea termed as "Mennodo" is introduced to better explain the triaxial and biaxial compressive strength of concrete of the specimen. The "Mennodo" is defined by the area which is calculated from direction cosine of Mohr's circle due to three dimentional principal stress.
