摘　　要：介绍了现有的半刚性钢框架柱有效(计算)长度系数的计算方法:一般屈曲方程法;转角位移方程法.分析、比较了此2种方法的计算结果后得出结论:屈曲方程方程法计算复杂,一般不采用;转角位移方程法计算简单,并且可以借助已有的结论及规范,因此采用较多.Three existing methods of calculating the effective length coefficient of semi-rigid steel frame,such as the method of general buckling equation and the method of intersection angle of displacement equation.And some analysis and comparison of the two methods are done,a conclusion is the first method has complex calculation and is not used generally,and the other method has relative simple calculation and can be used with the existing conclusions and standard,and is used more.
