摘要
依据弯矩分配法和剪力分配法中的基本概念,在进行刚架结构内力分析时,将刚架变形分为主动变形和被动变形。在此基础上,对于主动变形引起的被动变形,采用迭代分析的方法,得出了收敛速度的影响因素及其表达式,并进行了相关讨论。讨论结果对刚架结构无论是定量计算还是定性分析,都具有实际应用价值。
In this paper, according to the basic concepts of both moment distribution method and shearing force distribution, the frame deformation is divided into two parts：active one and passive one when internal force of frame structure is analyzed. Based on this division, with the method of iteration , the influencing factors and formulas for convergence speed are deduced and discussed. The conclusion has application value not only for quantitative calculation but also for qualitative analysis of frame structures .
