BIAXIAL TENSILE WEAKENING EFFECT OF THE STONY-GRAIN CONCRETE

摘要: 通过实验得到，混凝土在双向拉伸下的强度与其在单向拉伸下的强度相比较，会出现很大弱化现象，弱化程度达１５％～３０％．这对当今大跨度的钢筋混凝土板、壳结构来说，是一个非常重要的课题．

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.
