This study first analyzes boundary condition of single column member and adopts relative joint bending stiffness ratio of AISC to find the effective length factor. For that a structural joint or connection is neither full rigid nor full hinge in practice, this study uses this concept to establish the semi-rigid joint model. This study then discusses the structural behaviors of tapered members results with those from and compares these previous studies.
