Abstract

When non-structural members are used as eccentric braces in real structures, flexural and torsional deformation of compression members may occur due to the eccentric joints to the braces. This paper clarifies the buckling behavior with web deformation for H-shaped compression members with laterally and rotationally eccentric braces. The elasto-plastic buckling stress is evaluated with the buckling curve for design codes using the modified equivalent slenderness ratio. Then the elastic buckling load with energy method is applied to the slenderness ratio. In addition, the relationship between the required rigidity and strength of braces is evaluated.
