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,根据各国不同的计算方法,以两个理想模型和一个实际工程为例,分析了长细比和偏心距对柱的偏心距增大系数的影响规律,比较了各国计算方法的差异,阐述了长柱的工作机理、破坏过程,为探索新的简化计算方法提供参考.
Eccentricity accreting factor is an important parameter for carrying capacity of the reinforced concrete slender columns. According to the calculation method of six countries, the influence laws of eccentricity accreting factor with an increase in slenderness ratio and eccentric distance are analysed by a case and two ideal model. Slender columns functional mechanism and failure process are expounded. The result can be a reference to establish new simplified calculation method.
