In this report, the plastic deformation behavior of H-shaped beam restrained on upper flange is discussed. First, from the examination of numerical buckling analysis, the effect of upper flange restraint for several buckling mode is described. And for the purpose of estimating more exactly the general slenderness ratio using as parameter for the plastic deformation capacity recently, the effect factor (function) of upper flange restraint that is obtained from approximation of the numerical analysis results is presented. Next, from the examination with the elastic plastic large displacement analysis for upper flange restrained or non-restrained H-shaped beam, the effect of upper flange restraint for clastic deformation behavior is explained. And the relationship between the general slenderness ratio and plastic deformation capacity is investigated. Last, the point to notice to estimate the plastic deformation capacity from the general slenderness ratio is discussed.
