| Abstract: | 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. |
