平面应力状态下混凝土的强度准则

Strength criterion of concrete under plane stress state

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 strength criterion for concrete under biaxial stresses is presented, which gives a unified formula for different combined stresses. The comparison between some experimental results and the calculated results from the new strength criterion is made, which demonstrates that the new criterion given in this paper is of a certain accuracy.
