摘　　要：偏心距增大系数是钢筋混凝土长柱承载力分析的重要参数。该文考虑混凝土材料弹塑性阶段的实际应力-应变关系,采用线性和非线性分析方法计算长柱截面弯矩增大系数。分析了偏心距增大系数在弹性和塑性阶段的变化趋势及机理。Eccentric magnified coefficient is an important parameter to analyze the bearing capacity of long reinforced concrete column.The article considers the practical stress - strain relationship of the elastoplastic stage of concrete material,calculates the bending moment amplification factor of long column by the linear and nonlinear analysis method,and analyzes the variation trend and mechanism of eccentric magnified coefficient in the elastoplastic stage.
