混凝土偏压构件极限承载力的非线性理论分析计算

The Nonlinear Analysis on Ultimate Loads of Concrete Members Under Eccentric Loads

根据混凝土材料的非线性的应力 -应变关系 ,采用非线性分析计算的方法 ,对矩形、圆形截面的混凝土偏心受压构件的极限承载力做了理论分析与计算 ,建立了荷载偏心对构件承载力影响折减系数的计算方法。

According to the practical stress and strain relations of concrete,the ultimate loads of circular section and rectangle section members under eccentric loads are calculated with nonlinear analysis method.A theoretical calculation method for a convert coefficient of the ultimate load by the influence of eccentric load is established.
