摘　　要：在研究斜腿钢框架的抗侧移刚度时,因其受力机制已经改变,故不能再用分析直腿钢框架的模式。现本文主要研究斜腿柱与横梁在抗弯刚度变化的条件下对计算长度系数的影响,将所得的计算长度系数绘制成图,通过图表的形式进行对比分析趋势,则可更加直接明了的反映其影响。In the study of resistance to lateral stiffness of the inclined leg steel framework, because of the force mechanism has been changed, therefore analysis of straight leg steel frame model can＇ t be used. This paper mainly study the ＇influence of inclined leg column and beam under the condition of changing bending stiffness on the calculation length factor, the calculated length coefficient map is drawn through the form of chart, which reflect its influence is more direct and clear.

关 键 词：抗侧移刚度 计算长度系数 图表法
