| Outline of Final Research Achievements |
Non-structural members such as roof purlin do not considered as lateral braces. They may not possess enough rigidity and strength to fully restrain lateral buckling deformation of H-shaped beams. Even so, non-structural members may be effective to increase a buckling load of structural members at some extent. Next, H-shaped beams connected to steel tensile braces are subjected to compressive axial forces in addition to flexural moment, so the buckling behavior is more unstable than that to only flexural moment. In this paper, The two results are described as follows, 1.The buckling strength for beams subjected to continuous braces as roof purlin due to bracing effect of roof purlin is larger than that no brace.2.When beams are connected by tensile brace, its horizontal load bearing capacity of steel structures including beams are larger than beams are not be connected by brace. But the buckling strength for beams subjected to tensile brace may be lower than no brace.
