针对平面应力状态下的混凝土材料 ,提出了一种新型的强度准则 ,该准则在混凝土不同的受力区给出了统一的表达式 .计算与试验结果的比较验证了新强度准则的可靠性 .
A new type of strength criterion is proposed for the concrete under plane stress, which gives a uniform expression in different stress regions of concrete. Comparing the calculated result with the experimental result verifies the reliability of the new strength criterion.
