摘要
对《混凝土结构设计规范》中双向偏心受压构件承载力的验算公式,不少文献都涉及了用应力叠加进行解释。但众所周知,在塑性阶段的极限承载力状态下应力叠加原理是不成立的。引进国外有关研究资料,对验算公式作出诠释。
Many documents involve the principle of superimposed stresses in explaining the formula of bearing capacity of two-way eccentric compression member in codes of civil Engineering of concrete structures. But it is well known that the principle of superimposed stresses is not correct under ultimate limit states of plastic stage. This article quotes foreign concerned research informations and explains the formula.
