This paper discusses the effective length factor of columns in Khorjini frames. In order to find this factor, a proper approximated method is proposed. In addition, accurate analysis is performed and the results are compared with those from the proposed technique. The comparison demonstrates the accuracy of presented FORMULATIONS. The proposed method is similar to Julian and Lawrence's, which is used for rigid frames. Keywords: Khorjini Frame, Effective Length, Bifuraction Load, Rotational Stiffness, Matrix Structural Analysis, Column Factor.
