摘要：

When the non-structural members such as folded-roof plate are directly jointed to the structural members, the non-structural members may be used as the eccentric bracings. This paper clarifies the effect of lateral and rotational restraint for continuously eccentric braces on buckling stress for H-shaped compression members. 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. Finally, the relationship between the rigidity and strength of bracings is expressed as the approximation.
