摘要
在结构塑性极限分析中常使用以内力表示的塑性条件。针对圆板,本文给出了在考虑应变软化(岩土类材料)时以弯矩表示的摩尔—库仓准则。该准则可应用于岩石,混凝土等材料构成的圆板的极限承载能力分析。
Expressions denoted with internal forces arc often used in the limit analysis in plastic stage. In this paper, the author proposes to use a moment expression of Mohr-Coulomb in the case of limit analysis of circular plates in plastic stage. This proposal is useful in the analysis of load carrying capacity of circular plates composed of rock or concrete.
