摘　　要：提出了一种改进的简化刚度法。通过引入塑性刚度折减系数 ,获得统一的单元刚度的表达式。与简化刚度法的双分量模型相比 ,该方法更加形象直观 。An improved simple method is proposed for analysis of reinforced concrete frames in which the plastic stiffness reduction parameters are induced and the individual element stiffness is united.The method has such advantages as direct and obvious when compared with the original simple method.

关 键 词：钢筋混凝土 框架 简化刚度 弹性刚度 塑性刚度
