Abstract: This paper shows from the experimental data that the concrete′s strength under the biaxial tension is lower than its uniaxial tensile strength. The weakening effect reaches 15%~30%. This is an important problem for the modern large span reinforced concrete plate and shell structure.

Key words: biaxial tension, weakening effect, stony-grain concrete, Hill theory
